    5.  25 years
    Answer: Option A.
    let the age of kunal and sagar be k and s  respectively
    Given : k - 6 / s -6 =6/5 => 5k -6s = -6..........(1)
    and : k+4 /s +4 = 11/10 =>10k - 11s =4..........(2)
    Solving (1)&(2)  we get s =16 years.
  8. A number X is 150 more than a second number, Y. If the sum of X and Y is 5 times Y, what is the value of Y.
