  2. 14
  3. 18
  4. 10
Show answer

Answer: A. Let Meena = m, Ravi = m/2. m/2 + 6 = (2/3)(m + 6) → m/2 + 6 = 2m/3 + 4 → m/6 = 2 → m = 12.

Sample Medium question 5

  1. 33
  2. 39
  3. 36
  4. 30
Show answer

Answer: A. m + d = 45 and m − 5 = 4(d − 5). So 45 − d − 5 = 4d − 20 → 5d = 60, d = 12 and m = 33.

Sample Hard question 7

Ten years ago a father was 12 times as old as his son; ten years from now he will be twice as old as his son. Find the son's present age.

  1. 14
  2. 15
  3. 10
  4. 12
Show answer

Answer: D. f − 10 = 12(s − 10) and f + 10 = 2(s + 10). Eliminating f: 12s − 110 = 2s + 10, so s = 12 (and f = 34).
