Question

salary of ravi and sumeet are in the ratio2:3 if the salary of each is increased by rs.4000 the new ratio becomes 40:57 what is summet persent salary

Answer 1

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