Question 3.

Raju bought a book for Rs. 35.65. He gave Rs. 50 to the shopkeeper. How much money did he get back from the shopkeeper?

Solution:

Total amount given to shopkeeper = Rs. 50

Cost of book = Rs. 35.65

Amount left = Rs. 50.00 – Rs. 35.65 = Rs. 14.35

Therefore, Raju got back Rs. 14.35 from the shopkeeper.

Question 4.

Rani had Rs. 18.50. She bought one ice-cream for Rs. 11.75. How much money does she have now?

Solution:

Total money = Rs. 18.50

Cost of ice-cream = Rs. 11.75

Amount left = Rs. 18.50 – Rs. 11.75 = Rs. 6.75

Therefore, Rani has Rs. 6.75 now.

Question 5.

Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?

Solution:

Total length of cloth = 20 m 5 cm = 20.05 m

Length of cloth used = 4 m 50 cm = 4.50 m

Remaining cloth = 20.05 m – 4.50 m = 15.55 m

Therefore, 15.55 m of cloth is left with Tina.

Question 6.

Namita travels 20 km 50 m every day. Out of this she travels 10 km 200 m by bus and the rest by auto. How much distance does she travel by auto?

Solution:

Total distance travelled = 20 km 50 m = 20.050 km

Distance travelled by bus = 10 km 200 m = 10.200 km

Distance travelled by auto = (20.050 – 10.200) km = 9.850 km

Therefore, 9.850 km distance is travelled by auto.

Question 7.

Aakash bought vegetables weighing 10 kg. Out of this, 3 kg 500 g is onions, 2 kg 75 g is tomatoes and the rest is potatoes. What is the weight of the potatoes?

Solution:

Weight of onions = 3 kg 500 g = 3.500 kg

Weight of tomatoes = 2 kg 75 g = 2.075 kg

Total weight of onions and tomatoes

= (3.500 + 2.075) kg = 5.575 kg

Therefore, weight of potatoes

= (10.000 – 5.575) kg = 4.425 kg

Thus, weight of potatoes is 4.425 kg.
