      Question

      A and B are two numbers. Their average is 360, and the

      sum of A and B is 140% of A. What percentage of A is the difference between A and B?
      A 40% Correct Answer Incorrect Answer
      B 20% Correct Answer Incorrect Answer
      C 29% Correct Answer Incorrect Answer
      D 18% Correct Answer Incorrect Answer

      Solution

      ATQ;
      Since A + B = 140% of A

      So, A : B = 5 : 3

      (A βˆ’ B) : A = 2 : 5

      Therefore,

      2/5 Γ— 100% = 40%
