Question 7

Rahul’s salary is 40% of Mohit’s salary. If Rahul’s salary is increased by 60% and Mohit’s salary is decreased by 20%, then Rahul’s salary will be how much percentage of Mohit’s salary?

Solution

Let Mohit's salary = Rs. $$100$$

=> Rahul's salary = $$\frac{40}{100}\times100=Rs.$$ $$40$$

Rahul's new salary after 60% increase = $$40\times\frac{160}{100}=Rs.$$ $$64$$

Similarly, Mohit's new salary after 20% decrease = $$100\times\frac{80}{100}=Rs.$$ $$80$$

$$\therefore$$ Required % = $$\frac{64}{80}\times100=80\%$$

=> Ans - (A)
