The present ages of Tim and Lee are in the ratio of 5:6 respectively. Seven years hence, the ratio of their ages will be 6:7 respectively. What is Tim's present age?	Pick
A) 40 years B) 32 years C) 35 years D) 34 years E) 39 years
Let x be the Tim's age.   And y be the Lee's age.   Then, x/y = 5/6 ===&gt; y = 6x/5   And, x+7/y+7 = 6/7   ==&gt; 7x+49 = 6y+42   ==&gt; 7x = 67-7   By substituting 7x=(36x/5)-7   ==&gt;35x-36x=-35   Therefore, x=35   ANSWER:35 years
