Now:
Father = x + 24
Daughter = x
In 12 years:
Father = (x + 24) + 12 = x + 36
Daughter = x + 12
Father = 2(Daughter)
x + 36 = 2(x + 12)
x + 36 = 2x + 24
36 - 24 = 2x - x
x = 12

Fang Juan :
X=F
Y=S
X+Y=62
X-5= 3(Y-5)
X-5 =3Y-15
X=3Y - 15+5
X= 3Y-10
SUBS
X+Y=62
3Y-10+Y=62
3Y+Y=62+10
4Y=72
Y= 18
SUBS AGAIN
X=3(18)-10
X= 54-10
X=44
C is the Answer
