A is 60% more than B. C is 55% more than the difference between A and B. If A is decreased by 40% and C is increased by 331⁄3%, then C is what percentage more than A (correct to one decimal place)?

  • A22.6%
  • B29.2%
  • C28.5%
  • D25.4%
Correct answer: B

Explanation

Let B = 100, so A = 160. A − B = 60 and C = 155% of 60 = 93. New A = 60% of 160 = 96 and new C = 93 × 4/3 = 124. C is more than A by (124 − 96)/96 × 100 = 29.2%.
