Question

88 litres of milk is bought at rs 50 per litre. if 10 liters of milk is lost by leakage and the remainder is sold at rs 55 per litre, find the gain or loss percent.

​

Answer 1

It cost 50*80=4000rs to buy the milk.

The amount earned by selling it is (88-10)*55=4290rs.

The gain is (4290-4000)/4000=0.072=7.25%
