Question

Hello friends can you answer question 8 please please

Answer 1

Answer

Let ,

Present age of son be X years

Present age of father be y years

ATQ,

Y-10=12(x-10)

12x-y=110.........(1)

Y+10=2(x+10)

2x-y=-10............(2)

Subtracting eq (2) from (1),we get,

[X=12]

Substituting value of x in eq (2),,

[Y=34]

Thus,

Present age of father is 34 years and present age of son is 12 years..

I hope it is right...
