      Question

      If the 4-digit number a34b is exactly divisible by 9, what

      is the least value of (a + b)?
      A 2 Correct Answer Incorrect Answer
      B 1 Correct Answer Incorrect Answer
      C 5 Correct Answer Incorrect Answer
      D 10 Correct Answer Incorrect Answer

      Solution

      ATQ,

      The sum of digits = a+3+4+b = a+b+7

      For divisibility by 9, a + b + 7 should be a multiple of 9.

      The smallest value of a + b that satisfies this condition is 2.

      Thus, least value of (a + b) = 2.
