Question

Aman's age is three times his son's age. Ten years ago he was five times his sons age . Find their present ages.( Please explain )

Answer 1

Step-by-step explanation:

first let man's age be x

and son's age be y

so,

3y=x

ten years ago(after 10 years both will be young so minus 10 from that... simple... then,)

5(y-10)=x-10

now, 5y-50=x-10

x-5y+40=0(eq 1)

x-3y=0(eq 2)

eq 1 - eq2

x-5y+40=0

-x+3y+0=0

ans is -2y+40=0

y=-40/-2=20

put value in eq 2

x-3(20)=0

x-60=0

x=60

best of luck!!!
