# Easy Ratios & Proportion Solved QuestionAptitude Discussion

 Q. Salaries of Ravi and Sumit are in the ratio $2:3$. If the salary of each is increased by Rs. 4000, the new ratio becomes $40:57$. What is Sumit's salary?
 ✖ A. Rs. 17,000 ✖ B. Rs. 20,000 ✖ C. Rs. 34,000 ✔ D. Rs. 38,000

Solution:
Option(D) is correct

Let the original salaries of Ravi and Sumit be Rs. $2x$ and Rs. $3x$ respectively.

then,

\begin{align*} \dfrac{2x+4000}{3x+4000}&=\dfrac{40}{57}\\ \Rightarrow 57\times (2x+4000)&=40\times (3x+4000)\\ 6x&=68,000\\ 3x&=34,000 \end{align*}

Sumit's present salary =$(3x+4000)$=Rs.$(34000+4000)$= Rs. 38,000

simple approach

2 : 3= difference is 1

40 ; 57 = difference is 17

sumit salary is 17*2 = 34000+ 4000 increase = 38 ans
