Profit and Loss Exercise 10A Solution :

Question no – (1)

Solution :

(a) C.P = Rs 20, S.P = Rs 26

Given, C.P = 20, S.P = 26

SP > CP,

∴ Profit = S.P – C.P

= 26 – 20

= 6

(b) C.P = Rs 58, S.P = Rs 49

Given, C.P = 38, S.P = 49

C.P > S.P

∴ Loss = C.P – S.P

= 58 – 49

= 9

(c) C.P = Rs 7.50, S.P = Rs 10

Given, C.P = 7.50, SP = 10

∴ S.P > C.P

Profit = S.P – C.P

= 10 – 7.50

= 2.50

(d) C.P = Rs 140, S.P = Rs 105

Given, C.P = 140, S.P = 105

C.P > S.P

∴ Loss = C.P – S.P

= 140 – 105

= 35

(e) C.P = Rs 8000, S.P = Rs 7,981

Given, C.P = 8000, S.P = 7981

Clearly, C.P > S.P

∴ Loss = C.P – S.P

= 8000 – 7981

= 19

Question no – (2)

Solution :

(a) C.P = Rs 38, Profit = Rs 6

∴ C.P = 38, Profit = 6

∴ S.P = C.P + Profit

= 38 + 6

= 448

(b) C.P = Rs 408, Loss = Rs 20

∴ C.P = 408, Loss = 20

∴ S.P = C.P – Loss

= 408 – 20

= 388

(c) C.P = Rs 12.50, Loss = Rs 1.50

∴ S.P = C.P – Loss

= 12.50 – 1.50

= 11

(d) C.P = Rs 720, Profit = Rs 53

∴ C.P = 720, Profit = 53

∴ S.P = C.P + Profit

= 720 + 53

= 773

Question no – (3)

Solution :

(a) S.P = Rs 82, Loss = Rs 10

∴ S.P = 82

∴ Loss = 10

∴ C.P = S.P = Loss

= 82 + 10

= 92

(b) S.P = Rs 176, Profit = Rs 15

∴ S.P = 176, Profit = 15

∴ C.P = SP – Profit

= 176 – 15

= 161 Rs

(c) S.P = Rs 439, Loss = Rs 48

∴ S.P = 439, Loss = 48

∴ C.P = 439 + 48

= 487

(d) S.P = Rs 1385, Profit = Rs 270

∴ S.P = 1385, Profit = 170

∴ C.P = 1385 – 270

= 1115

Question no – (4)

Solution :

Given, C.P = 5890, S.P = 6672

∴ S.P > C.P

∴ Profit will be,

= 6672 – 5890

= 782 Rs

Question no – (5)

Solution :

∴ C.P = 21700, He spent 540 on its repair

∴ New C.P will be,

= (21700 + 540)

= 22240 Rs

∴ S.P = 24000

∴ S.P > C.P

∴ Profit will be,

= (21700 + 540)

= 1760 Rs.

Profit and Loss Exercise 10B Solution :

Question no – (1)

Solution :

(a) CP = Rs 1440 and SP = Rs 1800

Given,  CP = 1440, SP = 1800

SP > CP

∴ Profit = 1800 – 1440

= 360

∴ Profit % = (360/1440 × 100) %

= 25%

(b) CP = Rs 100 and SP = Rs 200

Given, CP = 100, SP = 200

∴ SP > CP, Profit = 200 – 100

∴ Profit % = (100/100 × 100)

= 100%

(c) CP = Rs 200 and SP = Rs 100

Given, CP = 200, SP = 100

CP > SP,

∴ Loss = 200 – 100

= 100

∴ Loss % = 100/200 × 100

= 50%

(d) CP =Rs 550, overhead expense

= Rs 250 and SP = Rs 900

Given, CP = 550, OE = 250, SP = 900

∴ Total CP = (550 + 250) = 800, SP = 900

∴ SP > CP, Profit = 900-800

= 100

∴ Profit % = 100/800 × 100

= 25/2%

Question no –  (2)

Solution :

∴ Profit% = 15%,

Total C.P = (1850 + 450) = 2300 Rs

∴ S.P = 100 + 15/100 × 2300

= 115 × 23

= 2645 Rs

Question no – (3)

Solution :

∴ Loss% = 18%, S.P = 287

∴ C.P = 100/100 – 18 × 87

= 100/82 × 287

∴ C.P = 350 Rs

Question no – (4)

Solution :

∴ Total C.P = 1200 + 650 = 1850, Loss % = 10%

∴ S.P = 100 – 10/100 × 1850

∴ S.P = 90 × 185/10

∴ S.P = 1664

Question no – (5)

Solution :

∴ Loss % = 15 %, S.P = 15300

∴ C.P = 100/100 – 15 × 15300

∴ C.P = 100/85 × 15300

∴ C.P = 18000

Question no – (6)

Solution :

∴ C.P = 180 – 30 = 150, Profit = 26%

∴ S.P = 100 + 26/100 × 150

∴ S.P = 120/100 × 150

∴ S.P = 189 Rs

Question no – (7)

Solution :

He bought 200 oranges

And 120 rupees for a score

∴ Total CP = (120 × 10)

= 1200

∴ 200 orange CP = 1200

∴ 1 orange CP = 1200/200

∴ 175 orange CP

= 1200 × 175/200

= 1050

∴ 25 are rotten left orange

= 200 – 25

= 175

∴ SP = 175 × 5 = 875

∴ C.P > S.P,

∴ Loss will be,

= 1200 – 875

= 325

∴ Loss%

= (325/1200 × 100)%

= 27 1/2%

Therefore, His loss percent will be 27 1/2%
