Question 82

# A milkman buys milk at Rs 24 per litre. He adds 1/5 of water to it and sells the mixture at Rs 32 per litre. What will be his gain (in %)?

Solution

CP = 5*24 = 120

he add 1/5th quantity = 1 litre of water

now total quantity = 6 litres

he sold at 32 per litre

SP = 6*32 = 192

gain = 72

%gain = $$\frac{72}{120} \times 100 = 60$$%

so the answer is option D.
