Present ages of X and Y are in the ratio 5:6 respectively. Seven years hence this ratio will become 6:7 respectively. What is X's present age in years?  Choose the correct choice from the following options
A) 35 years  B) 17 years  C) 77 years  D) 88 years  E) 16 years
Let the present ages of X and Y be 5x and 6x years respectively.   Then, (5x + 7)/(6x + 7) = 6/7   7(5x + 7) = 6(6x + 7) =&gt; x = 7   X's present age = 5x = 35 years.   35 yearsnswer:35 years
