    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 present salary?

    A) Rs 32000

    B) Rs 34000

    C) Rs 38000

    D) Rs 40000

    E) None of these

    Correct Answer: C

    Solution :

    Explanation Option (c) is correct. Let the original Salaries of Ravi and Sumit is 2x and 3x. So as per question \[\frac{2x+4000}{3x+4000}=\frac{40}{57}\] \[\Rightarrow \]\[57\left( 2x+4000 \right)=40\left( 3x+4000 \right)\] \[\Rightarrow \]\[6x=68000\] \[\Rightarrow \]\[3x=34000\] Sumit Salary \[=3x+4000=34000+4000=38000\]
