Question

a man buys 10 litre of petrol for rupees 420 how much petrol could he have bought for the same amount if there two rupees less per litre

Answer 1

Given: A man buys 10 litre of petrol for rupees 420.

To find: How much petrol could he have bought for the same amount if there two rupees less per litre.

Solution:

• Now we have given that a man buys 10 litre of petrol for rupees 420.

• That means for 1 litre the price will be:

              Rs 420 / 10 = Rs 42

• Now if Rs 2 are less, then the price will be Rs 40 per liter.

• So for 10 litres it would be 40 x 10 = Rs 400

• Now the amount saved is Rs 420 - Rs 400 = Rs 20

• So for Rs 20 more 1/2 litres can be used.

              10 + 1/2 = 21/2 litres can be bought.

Answer:

           So ten and half litres will be bought if 2 Rs is less.
