      36% of one number is equal to 24% of another number. If the

      sum of both numbers is 420, what is the difference between them?
      A 45 Correct Answer Incorrect Answer
      B 84 Correct Answer Incorrect Answer
      C 50 Correct Answer Incorrect Answer
      D 33 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the numbers be ‘x’ and ‘y’ respectively.

      According to the question,

      ⇒ 0.36x = 0.24y

      ⇒ x/y = 0.24 / 0.36 = 2/3

      So the numbers are in the ratio 2 : 3

      Sum of the numbers = 2 + 3 = 5 units = 420

      ⇒ 1 unit = 420 ÷ 5 = 84

      ⇒ Difference = (3 – 2) units = 1 unit = 84
