Question 82

A milkman buys milk at Rs 25 per litre and adds 1/4 of water to it and sells the mixture at Rs 26 per litre. His gain (in %) is?

Solution

Let he buy 4 litres

CP = 4*25 = 100

he add 1/4th quantity = 1 litre of water

now total quantity = 5 litres

he sold at 26 per litre

SP = 5*26 = 130

gain = 30

%gain = $$\frac{30}{100} \times 100 = 30$$%

so the answer is option C.
