Answer:
Let
the present age of mother be x
And the present age of daughter be y
A/Q
x-10=12(y-10)
x-10=12y-120
x-10+120=12y
x+110=12y
x=12y-110
And
x+10=2(y+10)
x+10=2y+20
x+10-20=2y
x-10=2y
x=2y+10
12y-110=2y+10
12y-2y=10+110
10y=120
y=12
x=12×12-110
x=34
So,
The present age of mother =34
The present age of daughter =12
