Question

Q93. A jar contains milk and water in ratio 8:x. When 5 litres of milk and 30 litres of water are added, the ratio becomes 1:1. Find x.

1. A. 6
2. B. 2
3. C. 5
4. D. 3 (Correct answer)
5. E. Can't be Determined

Correct Answer

Option D — 3

Detailed Solution & Explanation

The correct answer is 3.

Key Points

• Let initial: milk=8k, water=xk.
• After adding: (8k+5) = (xk+30) → k(8–x) = 25. Try x=3: 5k=25 → k=5; milk=40, water=15 → after adding: 45:45 = 1:1 ✓.
