rs 18 per liter

Answer 2

Cost price of milk is Rs. 15 per liter.

Step-by-step explanation:

Since we have given that

Selling price of milk = Rs. 18 per liter

Gain % = 20%

So, we need to find the cost price of milk per liter.

So, Cost price is given by

$\dfrac{100}{100+20}\times 18\\\\=\dfrac{100}{120}\times 18\\\\=15$

Hence, Cost price of milk is Rs. 15 per liter.
