      Question

      A number leaves a remainder of 12 when divided by 19.

      What will be the remainder when three times that number is divided by 19?
      A 13 Correct Answer Incorrect Answer
      B 23 Correct Answer Incorrect Answer
      C 17 Correct Answer Incorrect Answer
      D 27 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Number = (19A + 12), where 'A' is a constant.

      Therefore, required remainder = [3 × (19A + 12)] ÷ 19

      = (57A + 36) ÷ 19

      = (57A + 19 + 17) ÷ 19 = 17
