# Moderate Ratios & Proportion Solved QuestionAptitude Discussion

 Q. The monthly salaries of two persons are in the ratio of $4:7$. If each receives an increase of Rs.25 in the salary, the ratio is altered to $3:5$. Find their respective salaries.
 ✖ A. 120 and 210 ✖ B. 80 and 140 ✖ C. 180 and 300 ✔ D. 200 and 350

Solution:
Option(D) is correct

Let the salaries be $4x$ and $7x$

Therefore,

\begin{align*} \dfrac{4x+25}{7x+25}&=\dfrac{3}{5}\\ 5(4x+25)&=3(7x+25)\\ 20x+125&=21x+75\\ x&=50 \end{align*}

Therefore, their salaries are $4×50$ and $7×50$ i.e., 200 and 350
