Question

2 year ago a father has five times as old as his son .2 years later his age will be 8 more than 3 time the age of the son . Find the present age of father andson

Answer 1

y-2=5x_______(1).

y+2=3x+8________(2).

subtracting both the equation equations:--

y+2-y+2=3x+8-5x.

4=8x+8.

8x=4-8.

x=-4/8.

x=-1/2.

Now, substitute this value in equation (1):--

y-2=5x.

y-2=5(-1/2).

y=-5/2+2.

y=-5+4/2.

y=-1/2.

Here we are getting negative ages which are not possible.

So father's age is 6 months and son's age is also 6 months.
