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 choices:	A) 35 years	B) 37 years	C) 16 years	D) 17 years	E) 18 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
