let present age of beeru is x and neeru is y
x/y = 3/4
x = 3y/4 --------------------(1)
after 5 years
(x+5)/(y+5) = 4/5
x+5 = 4(y+5)/5
put x = 3y/4
15y + 100 = 16y + 80
y = 20
x = 3*20/4 = 15
x/y = 3/4
x = 3y/4 --------------------(1)
after 5 years
(x+5)/(y+5) = 4/5
x+5 = 4(y+5)/5
put x = 3y/4
15y + 100 = 16y + 80
y = 20
x = 3*20/4 = 15
