Question

A milk merchant buys 50 litres of milk at the rate of rs 40 per litre and mixes 5 litres of water in it. If he sells this mixture at the rate of rs 42 per litre, then what is the profit percentage for the dealer?

Answer 1

Cost of 50l milk at the rate of ₹ 40/l =
50 * 40 = 2000
Amount of milk formed after mixing water =
50 +5 = 55 l
Cost of 55l milk at the rate of ₹ 42/l = 55 * 42 = 2310
Profit for the dealer = 2310 - 2000 = 310
Profit % =
$100 \times \frac{310}{2000}$
= 15. 5 %
