Ratio,Proportion, Percentages and Discounting Q.8

  • Option : B
  • Explanation : Let Y’s salary = 100, then X’s salary = 50
    X’s new salary = 50 × 3/2 = 75
    Y’s new salary = 100 × 5/4 = 125
    Combined old salary = 100 + 50 = 150
    New combined salary = 75 + 125 = 200
    Increase in combined salary = 50
    Percentage increase = 50/150 × 100 = 33.33%
