Question

if sum of age of father and his son in year is 45 and thrice the difference of their age in year is same as sum of age. find the age of father

Answer 1

let X= age of father and y= age of son.

then we get x+y = 45 and 3(x-y) = 45

Now, solving the equation we get x=30 years

Answer 2

Let age of father be=x

Sum=45

Therefore, Difference=15

Thus, Let age of Son be=x-15

ATQ

x+(x-15)=45

=2x-15=45

=2x=45+15

=x=60/2

=x=30.

Age of father= 30 years

Age of son= 15 years
