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%
