Question

Bashir has ₹100. He spends three-fourth of the money on prawns. Prawns costs ₹150 per kg. How many kilograms of prawns did he buy?

Answer 1

Cost of prawns per kg = ₹75
Amount of money that Basheer has = ₹100
Money spent on prawns = $\frac{3}{4}$ of total money
= 3 quarters of total money

1 quarter of ₹100 = ₹25
3 quarters of ₹100 = ₹75
So, the money spent on prawns = ₹75

Weight of prawns that can be bought for ₹150 = 1 kg
Weight of prawns bought for ₹75 = $\frac{1}{2}$ kg
