Heya mate, Here is ur answer
Let the ages of two brothers be x and y.
x-y=3
x=3+y--------(1)
Five years ago,
x's age = x-5
y's age = y-5
A/Q,
y-5= 2/5(x-5)
y-5=2x-10/5
5(y-5)=2x-10
5y-25=2x-10
5y-2x=-10+25
5y-2x=15
From equation 1 , we have x=3+y,
so 5y-2(3+y)=15
5y-6-2y=15
3y=15+6
3y=21
y=21/3
y=7 .
x=3+y
x=3+7
x=10
