Q78. The number of balls in bag F is 25% more than red balls in E, and the ratio of red balls in A to blue balls in F is 2:1. Find the red balls in F.

  1. A. 685
  2. B. 680
  3. C. 630
  4. D. 620
  5. E. 600 (Correct answer)

Correct Answer

Option E — 600

Detailed Solution & Explanation

The correct answer is 600.

Key Points

  • Total(F) = 1.25 × Red(E) = 1.25 × 540 = 675.
  • Red(A):Blue(F) = 2:1 → Blue(F) = Red(A)/2 = 150/2 = 75. Red(F) = 675 – 75 = 600.
