    Answer : Option D

    Explanation :

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

     

     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.
