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?
Select the correct option:
A) 35 years
B) 77 years
C) 55 years
D) 44 years
E) 33 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
