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?

1Rs. 17,000
2Rs. 20,000
3Rs. 25,500
4Rs. 38,000

Answer:- 1

Explanation:-

Solution:

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

Then, \frac{2 x + 4000}{3 x + 4000} = \frac{40}{57}

${\text{Then}},\,\frac{{2x + 4000}}{{3x + 4000}} = \frac{{40}}{{57}}$ ⇒ 57(2x + 4000) = 40(3x + 4000)
⇒ 6x = 68,000
⇒ 3x = 34,000
Sumit's present salary = (3x + 4000) = Rs.(34000 + 4000) = Rs. 38,000.
