Question

If salary of $X$ is $20\%$ more than salary of $Y$, then by how much percentage is salary of $Y$ less than $X$?

• A. $25$
• B. $20$
• C. $\frac{50}{3}$
• D. $\frac{65}{4}$

Answer 1

The correct option is C $\frac{50}{3}$

$X$ salary is $20\%$ more than salary of $Y$.

If $Y$ get Rs. $100$, then $X$ gets Rs. $120$.
If $X$ gets Rs. $120$. then $Y$ gets Rs. $20$ less.
Therefore, $Y$ gets $\frac{20}{120}\times 100\%$ i.e., $\frac{50}{3}\%$ less than $X$.
