The ratio of the present age of two brothers is 1:2 and 5 years back, the ratio was 1:3. What will be the ratio of their ages after 5 years? Choose the correct answer:
A) 3:6	B) 3:2	C) 3:5	D) 3:1	E) 3:2
Let the present ages of the two brothers be x and 2x years respectively.   Then, (x - 5)/(2x - 5) = 1/3   3(x - 5) = (2x - 5) =&gt; x = 10   Required ratio = (x + 5) : (2x + 5) = 15 : 25   = 3:5   Answer:3:5
