let the age of father be x and
son be y
ATQ
two years ago,
age of father =x-2
age of son=y-2
x-2=3 (y-2)
x-2=3y-6
x-3y=-6+2
x-3y=-4..........(1)
after 2 years,
age of father =x+2
age of son =y+2
2 (x+2)=5 (y+2)
2x+4=5y+10
2x-5y=10-4
2x-5y=6..........(2)
from eqn.(1)
x=3y-4......(A)
put value of x in eqn 2
2 (3y-4)-5y=6
6y-8-5y=6
y=6+8
y=14
put value of y in eqn. A
x=3×14-4
x=42-4
x=38
therefore,
Present age of father=38
Present age of son=14
