      then the value of (3x β€” 2y), for the smallest value of y, is:
      A 18 Correct Answer Incorrect Answer
      B 20 Correct Answer Incorrect Answer
      C 9 Correct Answer Incorrect Answer
      D 22 Correct Answer Incorrect Answer

      Solution

      43x1145y2 5y2 must be divisible by 8 ∴ y = 1 ∴ 512 is divisible by 8 and for divisibility by 11 of 43x114512 (4+x+1+5+2) – (1+4+1+3) should be multiple of 11 ∴ x = 8 Now 3x-2y = 3Γ—8-2Γ—1 = 24-2 = 22
