A milk vendor mixes water with pure milk. If he sells the mixture at the cost price of pure milk and makes a profit of 25%, what is the ratio of water to pure milk in the mixture?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1:4.
25% = 1/4 ⇒ CP/SP = 4/5
Profit = 5 - 4 = 1 unit (which is water)
So, ratio of water : pure milk = 1 : 4
