Profit, Loss and Discount Exercise 8(A) Solution :

Question no – (1)

Solution : 

Selling Price of 10 note-books,

= (4.75 × 10)

= 47.50 Rs.

∴ Gain

= (47.50 – 40)

= 7.50 Rs.

∴ Gain %,

= (7.50/40 × 100)

= 18 3/4%

Therefore, her gain percent will be  18 3/4%.

Question no – (2) 

Solution : 

Let, number orange bought 12.

Cost Price of orange,

= (3/4 × 12)

= 16 Rs

Selling, Price of oranges,

= (4/3 × 12)

= 9 Rs

Profit,

= (16 – 9)

= 7 Rs

Profit %,

= (7/9 × 100)%

= 77 7/9%

Hence, his profit percent will be 77 7/9%.

Question no – (3) 

Solution : 

L.C.M of 15, 12 is 60

Let, articles bought 60,

Now, the Cost Price of articles,

= (60× 112.50/15)

= 450 Rs

∴ Selling Price of articles

= (108/12 × 60)

= 540 Rs

(i) Gain,

= (540 – 450) Rs

= 90 Rs

∴ Gain%

= (90/450 × 100)

= 20%

(ii) To make profit Rs 75 the number of articles needed to be sold

= (60/90 × 75)

= 50

Thus, 50 articles need to be sold.

Question no – (4) 

Solution : 

Cost Price of bicycles,

= (162 + 18)Rs

= 180 Rs

Selling Price = 207 Rs

Profit,

= (207 – 162)

= 45 Rs

∴ Gain %,

= (45/180 × 100)

= 25%

Therefore, his gain percent will be 25%

Question no – (5) 

Solution : 

Total Cost Price,

= (4800 + 1200)

= 6000 Rs

Selling Price = 5820 Rs

∴ Loss,

= (6000 – 5820)Rs

= 180 Rs

∴ Loss%,

= (180/6000 × 100)

= 3%

Therefore, his loss percent will be 3%

Question no – (6) 

Solution : 

As per the given question,

Selling Price = 3600

(i) Gain,

= (3600 × 1/6)

= 600 Rs

(ii) Cost Price,

= (3600 – 600)

= 3000 Rs

(iii) Gain %,

= 600/3000 × 100

= 20%

Question no – (7) 

Solution : 

According to the given question,

Selling Price = 5500

∴ Loss = (1/10 × 5500)

= 550 Rs

∴ Cost Price = (5500 + 550)

= 6050 Rs

∴ And Loss %,

= 550 × 100/6050

= 9 1/11%

Question no – (8) 

Solution : 

Let, Cost Price = 1

∴ Selling Price,

= 1 × 4/5

= 4/5

∴ Loss,

= 1 – 4/5

= 1/5

∴ Loss %,

= (1/5/1 × 100)

= 20%

Therefore, the loss percent will be 20%.

Question no – (9) 

Solution : 

Let, Selling Price = 1

Cost Price = 1 × 4/5

= 4/5

∴ Gain,

= 4 – 4/5

= 1/5

∴ Gain %,

= 1/5/4/5 × 100

= 25%

Therefore, the gain percent will be 25%.

Question no – (10) 

Solution : 

Let, Cost Price of goods = 100 Rs

Selling Price = 80 Rs

∴ Loss,

= (100 – 800

= 20 Rs

∴ Loss %,

= (20/100 × 100)

= 20%

Therefore, his loss percent will be 20%.

Question no – (11) 

Solution : 

Let, Selling Price = 100 Rs

Cost Price = 90 Rs

∴ Gain = 10 Rs

∴ Gain %

= (10/90 × 100)

= 11 1/9%

Therefore, loss percent will be 11 1/9%.

Question no – (12) 

Solution : 

Let, Selling Price = 100 Rs

30% of Selling Price = 30 Rs

Cost Price = (100 – 30)

= 70 Rs

Profit = 30

Now, the Profit %,

= (30/70 × 100)

= 42 6/7%

Therefore, the profit percent will be 42 6/7%

Question no – (13) 

Solution : 

As per the given question,

Cost Price of 300 eggs,

= (300 × 80)

= 24000 p

= 240 Rs

After broken remaining eggs,

= (300 – 30)

= 270

∴ Selling Price of eggs = (270 × 10)

= 270 Rs

Now, his Gain,

= (270 – 240)

= 30

∴ His Gain %,

= (30/240 × 100)

= 12.5%

Therefore, shopkeepers gain percent will be 12.5%.

Question no – (14) 

Solution : 

Loss = x/10

= 9x/10 Rs

∴ 9x/10 = 405

= x = 405 × 10/9

= 450 Rs

∴ Cost Price = 450 Rs ….(i)

(ii) First, the Loss = 450/10

= 45 Rs

∴ Now the Loss %

= (45/450 × 100)

= 10%

Question no – (15) 

Solution : 

Let, Cost Price = x Rs;

Selling Price = (x + x/9) Rs

= 10x/9 Rs

∴ 10x/9 = 250

= x = 9 × 250/10

= 225 Rs

∴ Cost Price of radio 225 Rs.

(ii) Profit = x/9

= 225/9

= 25

∴ Now the Profit %,

= (25/225 × 100)

= 11 1/9%

= 0.8%

Therefore, his profit percent will be 0.8%

Question no – (9) 

Solution : 

1st, tape recorder, S.P. = 990 Rs

Gain = 10%

C.P = (100/110 × 990) Rs

= 900 Rs

In 2nd, tape recorder,

S.P = 990;

Loss = 10%

C.P = (100/90 × 990)

= 1100 Rs

Total C.P of tape recorder,

= (1100 + 900)

= 2000

Total S.P of tape recorder,

= (990 + 990)

= 1980 Rs

∴ Loss,

= (2000 – 1980)

= 20 Rs

∴ Loss %,

= (20/2000 × 100)

= 1%

Therefore, Mr. Sinha loss percent will be 1%

Question no – (10) 

Solution : 

As per the given question,

(i) C.P. tape-recorder,

= 100 × 2760/115

= 2400

(ii) S.P. of CD player = 3240

C.P. = (100/90 × 3240)

= 3600 Rs

Total C.P. = (2400 + 3600)

= 6000

Total S.P.= (2760 + 3240)

= 6000 Rs

C.P. = S.P.

There is no gain or no loss in transaction.

C.P = (100/120 × 960)

= 800 Rs

Therefore, John paid for article 800 Rs.

Profit, Loss and Discount Exercise 8(C) Solution :

Question no – (1) 

Solution : 

Here, Cost Price of 1 pen = 28/5

= 5.60

Profit = 25%

(i) ∴ Selling Price of 1 pen,

= (125/100 × 5.60)

= 7 Rs.

(ii) ∴ Selling Price of 3 pens,

= (3 × 7)

= 21 Rs.

Hence, the Selling Price of 1 pen 7 Rs and 3 pen 21 Rs.

Question no – (2) 

Solution : 

S.P of 1 orange = 3/4

Gain = 50%

S.P = C.P × 150/100

C.P of 10 orange

= 100 × SP/150

= 100 × 3/4/100

= 1/2

(i) ∴ C.P of 4 orange = 4/2

= 2

(ii) ∴ C.P of 1 orange = 1/2

(iii) ∴ S.P of 1 orange = 3/4

(iv) ∴ In gain is Rs 24, no of oranges,

= 1/1/4 × 24

= 1/1× 4 × 24

= 96

Therefore, the number of oranges will be 96.

Question no – (3) 

Solution : 

As per the question we know,

S.P of 12 articles = 80

33 1/3% gain = 100/3%

C.P = 100/100 + 100/3 × 80

= 100/300 + 100 × 80

= 100 × 3/400 × 80

= 60 Rs

Rs 60 is the C.P of 12 articles.

Rs 90 is the C.P of 12 articles,

= (12/60 × 90)

= 18 article.

Hence, the number of article will be 18 article.

Question no – (4) 

Solution : 

Here, C.P of 20 articles = S.P of 10 articles.

C.P of 16 article = Rs 16

S.P of 16 articles = 20 Rs

∴ Gain = (20 – 16)

= 4 Rs

∴ Gain % = 4/16 × 100

= 25%

Therefore, the gain percent will be 25%

Question no – (6) 

Solution : 

Here, Let, C.P of 1 pen = 1

Cost Price of 8 pens = 8

∴ Loss % = (2/8 × 100)

= 25%

Hence, his loss percent will be 25%.

Question no – (7) 

Solution : 

After 12% profit,

Cost Price,

= (112/100 × 4500)

= 5040 Rs

Cost Price of 1/3rd of rice,

= (1/3 × 4500)

= 1500 Rs

Gain 10%

Selling Price on 1/3rd,

= (110/100 × 1500)

= 1650 Rs

Remaining cost price,

= (4500 – 1500)

= 3000 Rs

Remaining Selling Price,

= (3390 – 3000)

= 390 Rs

Now, the Gain %

= (390/3000 × 1000

= 13%

∴ (i) Selling Price of rest of rice = 339 Rs

∴ (ii) % profit on rest = 13%

Question no – (8) 

Solution : 

After gain, S.P of the books,

= (110/100 × 600)

= 660 Rs

1/4 sold then C.P of 1/4th,

= (1/4 × 600)

= 150 Rs

Loss = 5%

Now the S.P of books,

= (95/100 × 150)

= 142.50 Rs

Now, C.P of the remaining note books,

= (600 – 150)

= 450 Rs

S.P of the same books,

= (660 – 142.50)

= 517.50 Rs

Question no – (9) 

Solution : 

Let, C.P of watch = 100

5% profit, S.P = 105

And, 11% profit, S.P = 111

Difference of S.P,

= (111 – 105)

= 6

Now, watch sold for Rs 24 more, the C.P of watch,

= (100/6 × 24)

= 400 Rs

Therefore, the cost price of the watch will be 400 Rs.

Question no – (10) 

Solution : 

Let, C.P of bicycle = 100

For 5% profit, S.P = 105

2nd, case C.P,

= (100 – 30/100 × 100)

= 70

After 305 profit, S.P,

= (70 + 70 × 30/100)

= 91 Rs

Two selling price difference,

= (105 – 91)

= 14 Rs

Now, if the difference 63 Rs then C.P of the bicycle,

= (100/14 × 63)

= 450 Rs

Therefore, the cost price of the bicycle was 450 Rs.

Question no – (11) 

Solution : 

Let, C.P = 100

Case I, After loss 8%,

S.P = 92 Rs

Case II, CP = (100 – 100 × 10/100)

= 90 Rs

After 20% profit, S.P,

= (120/100 × 90)

= 108 Rs

Difference of two selling price

= (108 – 92)

= 16 Rs

Now, it the difference 36 Rs then C.P,

= (100 × 36/16)

= 225 Rs

Therefore, the cost price of the article is 225 Rs.

Profit, Loss and Discount Exercise 8(D) Solution :

Question no – (1) 

Solution : 

As per the given question,

M.R.P = 1300

S.P = 1144

Discount,

= (1300 – 1144)

= 156 Rs

∴ Discount %,

= (156/1300 × 100)

= 12%

Therefore, the discount percent will be 12%.

Question no – (2) 

Solution : 

According to the given question,

M.R.P = 23,600

Discount = 8%

∴ Selling Price

= 23600 × 92/100

= 21,712 Rs

Thus, its selling price is 21,712 Rs.

Question no – (3) 

Solution : 

Here, List-price of watch = 1400 Rs

Discount = 9%

∴ Discount,

= (1400 × 9/100)

= 126 Rs

∴ S.P = (1400 – 126)

= 1274 Rs

Therefore, the discount will be 126 Rs and selling price will be 1274 Rs.

Question no – (4) 

Solution : 

As per the question we know,

S.P of article 248.50

Discount = 10%

Let, M.R.P = 100

Discount = 10 Rs

∴ S.P = (100 – 10)

= 90 Rs

If, S.P 90 then list price 100 Rs

∴ S.P 248.50 then list price

= 100 × 248.50/90

= 276.11 Rs (approx.)

Hence, list price of the article will be 276.11 Rs (approx.)

Question no – (5) 

Solution : 

Given, Cost Price of article = 450 Rs

(i) M.R.P = (120/100 × 450)

= 540 Rs

(ii) Discount,

= (10/100 × 540)

= 54 Rs

Selling Price = (540 – 540

= 486 Rs

(iii) S.P = 496.80 (gain)

∴ Discount,

= (9540 – 496.800)

= 43.20 Rs

∴ Discount %,

= (43.20/540 × 100)

= 8%

Question no – (6) 

Solution : 

According to the question,

List price = 800

D = 15%

∴ Discount,

= (800 × 15/100)

= 120 Rs

(i) Selling Price,

= (800 – 120)

= 680

(ii) If profit 13 1/3% 40/3% then,

C.P = (100/100 + 40/3 × 680)

= 100/340/3 × 680)

= (3/340 × 100 × 680)

= 600 Rs

Therefore, the cost price of the article will be 600 Rs

Question no – (7) 

Solution : 

As per the question,

M.P = 2250 Rs

(i) Selling Price,

= (2250 × 88/100)

= 1980 Rs

∴ The selling price of the article will be 1980 Rs.

(ii) Profit = 10%

∴ Cost Price,

= (100/110 × 1980)

= 1800 Rs

∴ The cost price of the article for the dealer will be 1800 Rs.

Question no – (8) 

Solution : 

Selling Price of article = 1440 Rs

Let, MRP 100x

Discount = 20%

∴ Selling Price = 100x × 80/100

= 80x

∴ 80x = 1440

= x = 1440/80

= 18

∴ MRP = (100 × 18)

= 1800 Rs

∴ The marked price of the article will be 1800 Rs

Selling Price = 1440

P = 25%

Now, Cost Price of the article,

= (100 × 1440/125)

= 1152 Rs

∴ The cost price of the article will be 1152 Rs

Question no – (9) 

Solution : 

Let, Cost Price = 100

MP = (100 + 30)

= 130 Rs

Discount = 10%

∴ D = 130 × 10/100

= 13 Rs

Selling Price = (130 – 13)

= 117 Rs

∴ His Gain,

= (117 – 100)

= 17 Rs

∴ His Gain %,

= (17/100 × 100)

= 17%

Therefore, gain percent of shopkeeper will be 17%.

Question no – (10) 

Solution : 

Cost Price of dress = 400 Rs.

Profit = (400 × 20/100)

= 80

∴ Selling Price,

= (400 + 80)

= 480 Rs

Let, MP = 100 Rs

Discount = 20%

∴ Discount = 20 Rs

S.P = (100 – 20)

= 80 Rs

If SP of dress Rs 80, the MP = 100

If SP of dress Rs 480, the MP,

= (100/80 × 480)

= 600 Rs

Therefore, marked price of the dress will be 600 Rs.

Question no – (12) 

Solution :

According to the given question,

Cost price = 2400 Rs

MRP = (2400 × 125/100)

= 3000 Rs

After 15% discount, SP

= (3000 × 85/100)

= 2550 Rs

∴ Now the Profit,

= (2550 – 2400)

= 150 Rs

∴ Profit percent (%)

= (150/2400 × 100)

= 25/4%

= 6 1/4%

Therefore, the profit will be 150 Rs and the profit percent will be 6 1/4%

Question no – (13) 

Solution : 

Here, cost price of 1 article = 450

Cost price of 30 article,

= (30 × 450)

= 13500

Cost Price of 1/3 article,

= (450 × 30/3)

= 4500 Rs.

Loss = 6%

Selling Price of 10 articles,

= 4500 × (100 – 6)/100

= 4230 Rs.

Remaining article cost price,

= (14850 – 4230)

= 10620

∴ Selling Price of 1 article,

= 10620/20

= 531 Rs

Therefore, each article need to sold at 531 Rs.

Question no – (14) 

Solution : 

Let, MP of an article = 100

Cost Price,

= 100 × 75/100

= 75

D = 15%

Selling Price,

= (100 – 15)

= 85

(i) MRP

= (2400 × 100/75)

= 3200 Rs

(ii) Selling Price,

= (3200 × 100/75)

= 2720

(iii) Profit,

= (2720 – 2400)

= 320 Rs

Now the Profit percent (%),

= (320 × 100/2400)

= 40/3%

Therefore, the profit percent will be 40/3%

Question no – (15) 

Solution : 

(i) 20% and 12%

Let, MP = 100 Rs

D = 20%,

D₂ = 12%

(a + b – ab/100)

= (20 + 12 – 20 × 12/100)

= 32 – 204/100

= (32 – 2.4)

= 148/5 Rs discount,

(ii) 10%, 20% and 20%

Successive discount 10%, 20%, 20%

Selling Price = 100 × (100 – 10) × (100 – 20) × (100 – 20)/100 × 100 × 100

= 100 × 90 × 80 × 80/100 × 100 × 100

= 576/10

∴ Total discount = 100 – 576/10

= 100 – 576/10

= 424/10

= 42.4%

(iii) 20%, 10% and 5%

Successive discounts = 20%, 10%, 5%

MP = 100 (LET)

Selling Price

= 100 × (100 – 20) (100 – 10) (100 – 5)/ 100 × 100 × 100

= 100 × 80 × 90 × 95/100 × 100 × 100

= 342/5

Total discount,

= (100 – 342/5)

= 500 – 342/5

= 158/5

∴ Single discount,

= 158/5%

= 31.6%

Question no – (16) 

Solution : 

(i) 80% and 80%

Let, MP = 100 Rs

Single discount of two successive discount

= 80 = 80 – 80 × 80/100

= 160 – 64

= 96%

(ii) 60% and 60%

Now, single of two successive discount

= 60 + 60 – 60 × 60/100

= (120 – 36)

= 84%

∴ Single discount 84%

(iii) 60% and 80%

Single discount of two successive discount,

= 60 + 80 – 60 × 80/100

= (140 – 48)

= 92%

Therefore, the single discount will be 92%

Profit, Loss and Discount Exercise 8(E) Solution :

Question no – (1) 

Solution : 

As per the given question,

Cost price = 540 Rs

Rate of tax = 8%.

∴ Total amount paid by Rajat,

= (540 + 540 × 8/100)

= 583.2 Rs

Thus, total amount paid by Rajat for the watch will be 583.2 Rs.

Question no – (2) 

Solution : 

Given, Cost price = 3,840 Rs

Tax = 345.60 Rs

∴ Percent of sale tax,

= 345.60 × 100/3840

= 9%

Therefore, the rate of tax will be 9%.

Question no – (3) 

Solution : 

According to the question,

Price of a washing machine = 13,530 Rs

Tax = 6%

∴ Cost price,

= (13530 × 100/110)

= 12,300 Rs

Therefore, the cost price of the washing machine will be 12,300 Rs.

Question no – (4) 

Solution : 

As per the question,

Cost Price of biscuits = 158 Rs

Tax 6% = (158 × 6/100)

= 9.48 Rs

∴ Total price = (158 + 9.48)

= 167.48 Rs

Cost Price of cosmetic goods = 354 Rs

∴ Tax 9% = (354 × 9/100)

= 31.86 Rs

Therefore, the total amount paid by Sarita will be 31.86 Rs.

Question no – (5) 

Solution : 

Selling Price of set = 13,407 Rs

Tax = 9%

Let, MRP = x

∴ Selling Price = x + 9x/100 = 13407

= 100x = 9x/100 = 13407

= 109x/100 = 13407

= x = 100 × 13407/109

= 12300 Rs

∴ MRP = 12300 Rs

∴ Its marked price will be 12300 Rs

Now, Tax = 13%

= (12300 × 13/100)

= 1599125

∴ Selling Price,

= (12300 + 1599)

= 13,899 Rs

∴ Discount of SP,

= (13899 – 13407)

= 492 Rs

Therefore, the discount on selling price will be 492 Rs.

Question no – (6) 

Solution : 

Let, list price = x

Sales tax = x × 10/100

= x/10

∴ Selling Price = x + x/10

= 11x/10

11x/10 = 8250

= x = 8250 × 10/11

= 7500 Rs

(i) Rate of sale tax = 15%

Selling Price  = 7500 × 115/100

= 8625 Rs

Increases = (8625 – 8250)

= 375 Rs

(ii) Tax = 6%

Selling Price  = (7500 × 106/100)

= 7950

∴ Customer will pay,

= (8250 – 7950)

= 300 Rs

(iii) Sale tax = (10 + 2)

= 12%

Selling Price,

= 7500 × 112/100)

= 8400 Rs

∴ Customer pay,

= (8400 – 8250)

= 150 Rs

(iv) Sale tax rate = (10 – 3) = 7%

Selling Price = 7500 × 107/100

= 8025 Rs

∴ Customer pay less,

= (8250 – 8025)

= 225 Rs

Question no – (7) 

Solution : 

In the given question,

Selling Price of bicycle = 1664

List Price = 1600

∴ Tax = (1664 – 1600)

= 64 Rs

Sales tax rate,

= 64 × 100/1600

= 4%

∴ New sale tax,

= (4 + 6)

= 10%

Amount of sales tax,

= 1600 × 10/100

= 160 Rs

∴ Now the selling price,

= (1600 + 160)

= 1760 Rs.

Question no – (8) 

Solution : 

Distance of sales tax,

= (9 – 6)

= 3%

∴ List price of TV,

= 780 × 100/3

= 26000 Rs

Therefore, the list price of the T.V will be 26000 Rs.

Question no – (9) 

Solution : 

Given, Sales tax = 10%

∴ Actual price,

= 21384 × 100/110

= 19440

Again rate of sale tax = 8%

Selling Price = (19440 × 108/100)

= 20995.20

∴ Profit = (21384 – 20995.20)

= 388.80 Rs

Therefore, the extra profit made by the dealer is 388.80 Rs.

Profit, Loss and Discount Exercise 8(F) Solution :

Question no – (1) 

Solution : 

(i) Intra state transactions

Rate = 12/2 = 6%

∴ CGST = 16000 × 6/100

= 960

∴ SGST = 16000 × 6/100

= 960 Rs

∴ Amount of bill,

= (16000 + 960 + 960)

= 17920 Rs

(ii) Inter-state transaction,

= (16000 × 12/100)

= 1920 Rs

∴ Taxable cost of goods,

= (16000 + 1920)

= 17920 Rs

Question no – (2) 

Solution : 

As per the given question,

Cost Price = 25000

GST = 5%

∴ John will pay,

= (25000 + 25000 × 5/100)

= 25000 + 1250

= 26250 Rs

Therefore, John will pay total 26250 Rs.

Question no – (3) 

Solution : 

Given, Cost of transaction = 30,000 Rs

And, discount is = 30%

= (30000 × 30/100)

= 9000 Rs

∴ (30000 – 9000) Rs

= 21,000 Rs

Given, GST = 28%

∴ (21,000 × 28/100)

= 5880 Rs

∴ Now the Amount will be,

= (21000 + 5880)

= 26880 Rs.

Therefore, the amount of bill will be 26880 Rs.

Question no – (4) 

Solution : 

(i) Cost of services = Rs 5,000, discount = 20% and GST = 12%

Cost of services = 5000 Rs

D = 20%;

GST = 12%

∴ (5000 × 20/100)

= 1000 Rs

∴ (5000 – 1000)

= 4000 Rs

Given GST = 12%

So, (4000 × 12/100)

= 480 Rs

∴ Amount = (4000 + 480)

= 4480 Rs

(ii) Cost services = Rs 12,500, discount = 40% and GST = 18%

Cost services = 12500 Rs

D = 40%

Discount = (12500 × 40/100)

= 5000 Rs

∴ (125000 – 5000)

= 7500 Rs

GST = 18%

∴ GST = (7500 × 18/100)

= 1350 Rs

∴ Amount = (7500 + 1350)

= 8850 Rs

Question no – (6) 

Solution : 

(i) 40 articles for Rs 800 each at 30% discount

∴ Total price,

= (40 × 800)

= 32000 Rs

Discount = 30%

∴ Discount,

= (32000 × 30/100)

= 9600 Rs

(32000 – 9600)

= 22400 Rs

(ii) 75 articles for Rs 1,000 each at 20% discount.

Price = (75 × 1000)

= 75000 Rs

D = 20%

= (75000 × 20/100)

= 15000 Rs

Paid = (75000 – 15000)

= 60,000 Rs

∴ Total Amount,

= (60,000 = 22400)

= 82400 Rs

GST = 12%

∴ Amount = (82400 + 82400 × 12/100)

= (82400 + 9888)

= 92288 Rs.

Therefore, the dealer at Mumbai pays 92288 Rs to dealer in Bihar.
