Answer:

Correct Answer: C

Solution:

  • Let Parul’s present age be 7x and Rohit’s present age be 5x. Then, $ 7x+5x+10=94 $

$ \Rightarrow $ $ 12x=84 $
$ \Rightarrow $ $ x=7 $ So, Parul’s present age $ =7\times 7=49,yr $ Rohit’s present age $ =5\times 7=35,yr $ After 14 yr Rohit’s age will be equal to parul’s present age.
