Correct Answer: 76.92%
Explanation:
The milkman sells the milk at cost price but makes a profit of 30%.
This is possible only because he is mixing water (which is free) with milk.
Let us assume:
Since he makes 30% profit:
⇒ Cost price of 1 litre of mixture = 100 / 1.30 ≈ Rs. 76.92
This means, the milk in the mixture is worth Rs. 76.92 and the remaining part (100 - 76.92 = Rs. 23.08) is water.
Calculate the % of milk in the mixture:
(76.92 / 100) × 100 = 76.92%
Answer: The percentage of milk in the mixture is approximately 76.92%.
