Question

5 years ago fathar 's ago was 5 times as old as his son and after 3 year he will be 3 times as old as his son find the present

Answer 1

x is a father's present age
y is a son's present age
5 years ago,
x-5=5(y-5)
x-5=5y-25
x=5y-20____eqn (1)
after 3 years ,
x+3=3(y+3)
x+3=3y+9
x=3y+6____eqn(2)
equating eqn(1) and(2)
//leftside is same,so equating
5y-20=3y+6
5y-3y=20+6
2y=26
y=13years
sub y=13 in eqn(1)
x=5y-20
x=5(13)-20
x=65-20
x=45
father's present age=45 years
son's present age=13 years

Answer 2

X is a father's present age

y is a son's present age

5 years ago,

x-5=5(y-5)

x-5=5y-25

x=5y-20____eqn (1)

after 3 years ,

x+3=3(y+3)

x+3=3y+9

x=3y+6____eqn(2)

equating eqn(1) and(2)

//leftside is same,so equating

5y-20=3y+6

5y-3y=20+6

2y=26

y=13years

sub y=13 in eqn(1)

x=5y-20

x=5(13)-20

x=65-20

x=45

father's present age=45 years

son's present age=13 years

this is the answer
