A milkman purchases milk at ₹'a' per litre and sells it at ₹1.5a per litre. Still he mixes 2 litres water with every 9 litres of pure milk. What is his profit percentage?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 250/3
The cost price of the milk = ₹a/litre
The selling price of the milk = ₹1.5a/litre
He sells 11 litres of the mixture in which 9 litres of milk and 2 litres of water is present.
The cost price of 9 litre milk = ₹ 9a
The selling price of the mixture = 11 × ₹1.5a = ₹16.5a
The profit = ₹16.5a - ₹9a = ₹7.5
Profit% = (7.5a/9a) × 100 = 250/3 %
