Q18
ArithmeticPercentage, Profit & Loss
If A exceeds B by 40%, B is less than C by 20%, then A : C is:
  1. a.28 : 25
  2. b.26 : 25
  3. c.3 : 2
  4. d.3 : 1

Answer: (A) 28 : 25

Take C = 100; then B = 80 and A = 80 × 1·4 = 112. So A : C = 112 : 100 = 28 : 25. Adding the percentages directly (40 − 20 = 20%) would wrongly suggest 6 : 5, and the other ratios do not fit.
