      A 12 Correct Answer Incorrect Answer
      B 15 Correct Answer Incorrect Answer
      C 18 Correct Answer Incorrect Answer
      D 10 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the number be 'y'.

      (66 - y) : (54 - y) = 4 : 3

      β†’ 3 Γ— (66 - y) = 4 Γ— (54 - y)

      β†’ 198 - 3y = 216 - 4y

      β†’ y = 18

      So, y = 18
