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?
38000
Let the original salaries of Ravi and Sumit be Rs. 2x and Rs. 3x respectively.
Then,
(2x+4000)(3x+4000)=4057
⇒57×(2x+4000)=40×(3x+4000)
⇒6x=68,000
⇒3x=34,000
Sumit′s present salary = (3x+4000)=Rs.(34000+4000)=Rs.38,000
