2. Rashid spent ₹ 35.75 for the Maths book and ₹ 32.60 for the Science book. Find the total amount spent by Rashid.
Solutions:
Rashid spent for the Maths book = ₹ 35.75
Rashid spent for the Science book = ₹ 32.60
\[ \displaylines{ 35.75 \\+ 32.60\\ \text{___________}\\68.35 \\ \text{___________}}\]
∴ The total amount of money spent by Rashid is ₹ 68.35.
3. Radhika’s mother gave her ₹ 10.50, and her father gave her ₹ 15.80. Find the total amount given to Radhika by the parents.

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.
Solutions:
Nasreen bought cloth for her shirt =3 m 20 cm =3.20 m
Nasreen bought cloth for her trouser =2 m 5 cm=2.05 m
\[ \displaylines{ 3.20 \\+ 2.05\\ \text{___________}\\5.25 \\ \text{___________}}\]
∴ The total length of cloth bought by Nasreen is 5.25 m.
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?
Solutions:
Distance walked by Naresh in the morning = 2 km 35 m = [(2 + 35/1000)] km = 2.035 km
Distance walked by him in the evening = 1 km 7 m = \([(1 + {7\over 1000})]\) km = 1.007 km
The total distance walked by Naresh is \[ \displaylines{ 2.035 \\+ 1.007\\ \text{___________}\\3.042 \\ \text{___________}}\]
∴ The total distance walked by Naresh is 3.042 km.
6. Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m on foot in order to reach her school. How far is her school from her residence?
Solutions:
Distance travelled by bus = 15 km 268 m = \([(15 + {268 \over 1000})]\) km = 15.268 km
Distance travelled by car = 7 km 7 m = \([(7 + {7 \over 1000})]\) km = 7.007 km
Distance walked by Sunita = 500 m = \({500 \over 1000}\) = 0.500 km
\[ \displaylines{ 15.268 \\+ 7.007\\+ 0.500 \\ \text{___________}\\22.775 \\ \text{___________}}\]
∴ The total distance of the school from her residence is 22.775 km.
7. Ravi purchased 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850 g flour. Find the total weight of his purchases.
Solutions:
Weight of rice = 5 kg 400 g = \([(5 + {400 \over 1000})]\) kg = 5.400 kg
Weight of sugar = 2 kg 20 g = \([(2 + {20 \over 1000})]\) kg = 2.020 kg
Weight of flour = 10 kg 850 g = \([(10 + {850 \over 1000})]\) kg = 10.850 kg
The total weight of his purchases is \[ \displaylines{ 5.400 \\+ 2.020\\+ 10.850 \\ \text{___________}\\18.270 \\ \text{___________}}\]
∴ The total weight of his purchases is 18.270 kg
