= 40.000 + 27.700 + 2.451

= 67.700 + 2.451

= 70.151

Question no – (3)

Solution :

(1) 85.96 – 2.345

= 85.960 + 2.345

= 83.615

(2) 632.24 – 97.45

Question no – (4)

Solution :

As per the given question,

Avinash travelled 42 km 365 m by bus

12 km 460 m by car and walked 640 m.

Now, By bus = 42 km 365 m

By car = 12 km 460 m

By walked = 640 m

Thus, 42 km 365 m + 12 km 460 m + 640 m

= (42 km + 12 km ) + (365 + 460 + 640) m

= 54 km + (1465 m)

= 54 km + (1 km 465 m)

= 55 km 465 m

Question no – (5)

Solution :

According to the given question,

Ayesha bought 1.80 m of cloth for her salwaar and 2.25 m for her kurta.

Thus, total cloth,

=1.80 m + 2.25 m

= 4.05 m

Since, for 1 m cloth = ₹120

Thus, for 4.05 m cloth,

= 4.05 * 120

= ₹ 486.00

Hence, she pay ₹ 486 to the shopkeeper.

Question no – (6)

Solution :

As per the question,

Sujata bought a watermelon weighing 4.25 kg

1 kg 750 g to the children in her neighborhood.

= 70400/1000

= 704/10

Practice Set (16) :

Question no – (1)

Solution :

Since, 317 × 45 = 14265

Therefore, 3.17 × 4.5

= 14.265

Question no – (2)

Solution :

Since, 503 × 217 = 109151

Therefore, 5.03 × 2.17

= 10.9151

Question no – (3)

Solution :

(1) 2.7 × 1.4

= 27/10 × 14/10

= 378/100

= 3.78

(2) 6.17 × 3.9

= 3528/1000

= 3.528

Question no – (4)

Solution :

As per the question,

Virendra bought 18 bags of rice, each bag weighing 5.250 kg.

Thus, 18 × 5.250

= 18/1 × 5250/1000

= 94500/1000

= 94.500

Therefore, he buy 94.500 kg rise altogether.

Since, for 1 kg = ₹48

Thus, for 94.5 kg = 48 × 94.5

= 48/1 × 945/10

= 39690/19

= ₹3969

Therefore, he will pay Rs 3969

Question no – (5)

Solution :

According to the question,

Vedika has 23.50 metres of cloth.

She make 5 curtains of equal size.

Since, for 1 curtains

= 4 m 25 cm

= 4.25 m cloth required

Thus, for 5 curtains

= 5 × 4.25 = 5/1 ×425/100

= 2125/100

= 21.25 m cloth required

Now, total cloth = 23.50 m

Required cloth = 21.25 m

Thus, 23.50 – 21.25 = 2.25 m

Hence, 2.25 m cloth is left.

Practice Set (17) :

Question no – (1)

Solution :

(1) 4.8 ÷ 2

= 48/10 ÷ 2/1

= 48/10 × 1/2

= 24/10

= 2.4

(2) 17.5 ÷ 5

= 175/10 × 1/5

= 35/10

= 3.5

(3) 20.6 ÷ 2

= 206/10 ×1/2

= 103/10

= 10.3

(4) 32.5 ÷ 25

= 325/10 × 1/25

= 13/10

= 1.3

Question no – (2)

Solution :

As per the question,

A road is 4 km 800 m.

Since, trees are planted on both its sides at intervals of 9.6 m

Now, 4 km 800 m

= 4 km + 800 m

= 4800 m

4800 ÷ 9.6 = 4800 × 10/96

= 48000/96

= 500

Thus, 2 × 500 = 1000

Hence, 1000 trees are planted on both it’s sides at intervals of 9.6 m

Question no – (3)

Solution :

According to the question,

Pradnya walks a distance of 3.825 km in 9 rounds of the path

Thus, 3.825 ÷ 9 = 3825/1000 ÷ 9/1

= 3825/1000 × 1/9

= 425/1000

= 0.425 km

Hence, she walk in one round is 0.425 km

Question no – (4)

Solution :

Since, 1 quintal = 100 kg

Thus, 0.25 quintal

= 0.25 × 100

= 25/100 × 100/1

= 25 kg

We have given that, a pharmaceutical manufacturer bought 0.25 quintal of hirada, a medicinal plant, for 9500 rupees.

Thus for 25 kg = ₹9500

So, for 1 kg

= 9500 /25

= ₹380

Therefore, for 100 kg

= 1 quintal

= 100 × 380

= ₹38,000

Therefore, the cost per quintal of Hirada Rs 8,000
