let age of gouri = x
age of mahesh =
5 years ago,
3(x-5) = y-5
3x - 15 = y- 5
3x - y = -5 + 15
3x - y = 10 – eq 1
after 10 years,
2(x + 10) = y + 10
2x + 20 = y + 10
2x - y = - 10 – eq 2
so, solve this equation
then,
x = 20
putting the value of x ,
3x - y = 10
3*20 - y = 10
60 - y = 10
- y. = 10 - 60
- y. = -50
y = 50
so age of gouri = 20
age of mahesh = 50
