      the ratio 5:9. What will be the sum of the numbers?
      A 25 Correct Answer Incorrect Answer
      B 65 Correct Answer Incorrect Answer
      C 56 Correct Answer Incorrect Answer
      D 39 Correct Answer Incorrect Answer

      Solution

      ATQ,
      Let the numbers be 5m and 9m.

      LCM of the numbers = 45m

      Given, 45m = 180

      So, m = 4

      Thus, the numbers are 20 and 36.

      Hence, the sum = 20 + 36 = 56.
