Hari is twice as old as his son 20 years ago he was four times as old as his son find the present age of each

Answer 1

HEY MATE!

__________________________

Explanation:-

let the age of hari's son be x.

and, the age of hari be 2x.

given: 20 years ago ..

age of hari's son = (x-20)

age of hari = 4(x-20)

now,

(2x-20) = 4(x-20)

2x-20 = 4x-80

2x-4x = -80+20

-2x = -60

(minus- minus cancelled).

2x=60

x= 60/2

x= 30.

so, the son's present age is 30 years

and , the hari's present age is 2×30=60 years.

Answer 2

Thanks for the asking questions

in this case we need to be let
the age of hari's son be x.
and, the age of hari be 2x.

given that - 20 years ago age of hari's son = (x-20) and age of hari = 4(x-20)

Then

(2x-20) = 4(x-20)

2x-4x = -80+20

-2x = -60

x= 60/2

x= 30.

so, the son's present age is 30

and , the hari's present age is =60
