In a mixture of 624 litres, the ratio of milk to water is 5 ∶ 3. The amount of water to be further added to the mixture so as to make the ratio of the milk to water 5 ∶ 4 will be:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 78 litres.
Given:
The initial ratio of milk to water = 5 ∶ 3
The amount of water to be further added to the mixture
So the new ratio of milk to water = 5 ∶ 4
Explanation:
So, the water added in the second mixture
⇒ {624/(5 + 3)} × (4 - 3)
⇒ 78 × 1
⇒ 78 litres
