Truck	3	500
Bus	6	300
Car	10	50
Auto Rickshaw	12	8
Two wheeler	25	5

Q.1. How much more fuel is bought for buses than for trucks?
Q.2. What is the total quantity of fuel filled from the petrol pump on that day?

Answer

Vehicle	No. of Vehicles	Quantity of Fuel in Each Vehicle (in litres)	Total Quantity of Fuel (in litres)
Truck	3	500	3 × 500 = 1,500
Bus	6	300	6 × 300 = 1,800
Car	10	50	10 × 50 = 500
Auto Rickshaw	12	8	12 × 8 = 96
Two wheeler	25	5	25 × 5 = 125

1. Fuel bought for buses = 1,800 l
Fuel bought for trucks = 1,500 l
Difference = 1,800 – 1,500 = 300
300 l more fuel is bought for buses than for trucks.
2. The total quantity of fuel filled from the petrol pump on that day is:
1,500 l + 1.800 l + 500 l + 96 l + 125 l

Question 34 Marks

The cost of some grocery items is given in the following table. Find the total cost of each item.

Item	Weight	Cost of 1 kg	Total cost
Rice	12 kg 500 g	₹ 60
Flour	7 kg 250 g	₹ 40
Sugar	5 kg	₹ 45
Chana dal	3 kg 600 g	₹ 70
Besan	4 kg	₹ 60
Jaggery	1 kg 400 g	₹ 50

Answer

Rice: Cost of 12 kg = 12 × ₹ 60 = ₹ 720
Cost of lkg (1,000 g) = ₹ 60
Cost of 500 g = ₹ 30
Therefore, cost of 12 kg 500 g = ₹ 720 + ₹ 30
= ₹ 750
Flour: Cost of 7 kg = 7 × ₹ 40 = ₹ 280
Cost of 1 kg (250 g + 250 g + 250 g + 250 g)
= ₹ 40 (10 + 10 + 10 + 10)
Cost of 250 g = ₹ 10
Therefore, cost of 7 kg 250 g = ₹ 280 + ₹ 10
= ₹ 290
Sugar: Cost of 5 kg = 5 × ₹ 45 = ₹ 225
Chana dal: Cost of 3 kg = 3 × ₹ 70 = ₹ 210
Cost of 1 kg (1000 g) = ₹ 70
Cost of 100 g = ₹ 7
Cost of 600 g = 6 × ₹ 7 = ₹ 42
Therefore, cost of 3 kg 600 g = ₹ 210 + ₹ 42
= ₹ 252
Besan: Cost of 4 kg = 4 × ₹ 60 = ₹ 240
Jaggery: Cost of 1 kg (1000 g) = ₹ 50
Cost of 100 g = ₹ 5
Cost of 400 g = 4 ×₹ 5 = ₹ 20
Cost of 1 kg 400 g = ₹ 50 + ₹ 20 = ₹ 70
Hence, the complete table is:

Item	Weight	Cost of 1 kg	Total cost
Rice	12 kg 500 g	₹ 60	₹ 750
Flour	7 kg 250 g	₹ 40	₹ 290
Sugar	5 kg	₹ 45	₹ 225
Chana dal	3 kg 600 g	₹ 70	₹ 252
Besan	4 kg	₹ 60	₹ 240
Jaggery	1 kg 400 g	₹ 50	₹ 70

Question 44 Marks

A juice vendor has a 5 l container of orange juice. Each glass has a capacity 250 ml.
(a) How many full glasses can he serve before the container becomes empty?
(b) If he has already served 10 glasses, how much juice is left?
(c) If 250 ml of juice is sold at `25, how much will he earn by selling 5 l juice?

Answer

(a) 1l = 1000 ml = 500 ml + 500 ml
= 250 ml + 250 ml + 250 ml + 250 ml
So, 4 full glasses can be served in 1Z.

1 l × 5 = 5 l
4 glasses × 5 = 20 glasses
Therefore, he can serve 20 full glasses before the container becomes empty.
(b) Total juice = 5000 ml
Juice in 10 glasses = 10 × 250 ml = 2500 ml
Juice left = 5000 ml – 2500 ml 2500 ml = 21 500 ml
(c) We know that 20 × 250 ml = 5000 ml(5 l)

250 ml × 20 = 5000 ml
₹ 25 × 20 = ₹ 500
Therefore, he will earn ₹ 500 by selling 5 l juice.
