**Question 2: Rashid spent Rs 35.75 for Maths book and Rs32.60 for Science book. Find the total amount spent by Rashid.**

**Answer 2:** Money spent for Maths book = Rs 35.75

Money spent for Science book = Rs 32.60

Total money spent = Rs 35.75 + Rs 32.60 = Rs 68.35

Therefore, total money spent by Rashid is Rs 68.35.

**Question 3: Radhika’s mother have her Rs10.50 and her father gave her Rs15.80. Find the total amount given to Radhika by the parents.**

**Answer 3:** Money given by mother = Rs 10.50

Money given by father = Rs 15.80

Total money received by Radha = Rs 10.50 + Rs 15.80 = Rs 26.30

Therefore, the total money received by Radha is Rs 26.30.

**Question 4: Nasreen bought 3 m 20 cm cloth for her shirt and 2 m 5 cm cloth for her trouser. Find the total length of cloth bought by her.**

**Answer 4:** Cloth bought for shirt = 3 m 20 cm = 3.20 m

Cloth bought for trouser = 2 m 5 cm = 2.05 m

Total length of cloth bought by Nasreen = 3.20 + 2.05 = 5.25 m

Therefore, the total length of cloth bought by Nasreen is 5.25 m

**Question 5: Naresh walked 2 km 35 m in the morning and 1 km 7 m in the evening. How much distance did he walk in all?**

**Answer 5:** Distance travelled in morning = 2 km 35 m = 2.035 km

Distance travelled in evening = 1 km 7 m = 1.007 km

Total distance travelled = 2.035 + 1.007 = 3.042 km

Therefore, the total distance travelled by Naresh is 3.042 km.

**Question 6: Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m by foot in order to reach her school. How far is her school from her residence?**

**Answer 6:** Distance travelled by bus = 15 km 268 m = 15.268 km

Distance travelled by car = 7 km 7 m = 7.007 km

Distance travelled on foot = 500 m = 0.500 km

Total distance travelled = 15.268 + 7.007 + 0.500 = 22.775 km

Therefore, total distance travelled by Sunita is 22.775 km.

**Answer 7:** Weight of Rice = 5 kg 400 g = 5.400 kg

Weight of Sugar = 2 kg 20 g = 2.020 kg

Weight of Flour = 10 kg 850 g = 10.850 kg

Total weight = 5.400 + 2.020 + 10.850 = 18.270 kg

Therefore, the total weight of Ravi’s purchase = 18.270 kg.

**Answer 3: **Total amount given to shopkeeper = Rs50

Cost of book = Rs35.65

= Rs14.35

Therefore, Raju got back Rs14.35 from the shopkeeper.

**Question 4: Rani had Rs18.50. She bought one ice-cream for Rs11.75. How much money does she have now?**

**Answer 4: **Total money = Rs18.50

Cost of Ice-cream = Rs11.75

**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?**

**Answer 5: **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?**

**Answer 6:** Total distance travel = 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 = 9.850 km

Therefore, 9.850 km distance travels by auto.

**Question 7: Aakash bought vegetables weighing 10 kg. Out of this 3 kg 500 g in onions, 2 kg 75 g is tomatoes and the rest is potatoes. What is the weight of the potatoes?**

**Answer 7:** 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 = 5.575 kg

Therefore, weight of potatoes = 10.000 – 5.575 = 4.425 kg

Thus, the weight of potatoes is 4.425 kg
