      income of C is 60% less than the sum of income of A and B. Income of C is what percent less than income of A?
      A 28% Correct Answer Incorrect Answer

      Solution

      Let, income of A, B and C is Rs. a, Rs. b and Rs. c respectively. According to question, a = 1.25b And, c = 0.4 × (a + b)
      = 0.4 × (1.25b + b)
      = 0.4 × 2.25b
      = 0.9b So, c/a = 0.9b/1.25b = 0.72 So, income of C is 28% less than income of A.
