Question 9
1 / -0.33

A vessel of 80 litres is filled with milk and water. 70% of milk and 30% of water is taken out of the vessel. It is found that the vessel is vacated by 55%. Find the initial quantity of milk and water.

A
50, 20

B
50, 30

C
30, 10

D
30, 20

Solution

Let the initial quantity of milk be x L

Since The total mixture is 80 L so the initial quantity of water be (80 - x) L

⇒ 70% of x + 30% of (80 - x) = 55% of 80⇒ 0.7x + 0.3 × (80 - x) = 0.55 × 80

⇒ x = 50

Therefore, Initial quantity of milk = 50 L and the initial quantity of water = 30 L
