Answer 2

Answer:

Explanation:

Let fathers age=x

Let sons age=y

Before 10 years

Father=(x-10)

Son=(x-10)

X-10=12(y-10)

X-10=12y-120

X-12y=110

And after 10 years

Father=(x+10)

Son=(y+10)

X+10 =2(y+10)

X+10=2y+20

X-2y=10

Now by substitution method

X=110+12y

Put in x-2y=10

110+12y-2y=10

-10y=-120

Y=12

And now

X=10+y

X=10+2(12)

X=10+24

X=34

So finally age of father=34yrs

And age of son=12yrs
