Show answer & explanation

Correct answer: E

Initial mixture is 72 liters with milk:water = 5:3, so milk = 45 liters and water = 27 liters.

After removing 40 liters, 32 liters remain with milk = 20 liters and water = 12 liters.

After adding x liters of pure milk, (20 + x) : 12 = 7 : 1, so 20 + x = 84 and x = 64.
