Answered by admin @


Ani's age = a
biji's age = b
ani's father, dharma's age = d
cathy's age = c
A/q
a-b =3____(1)
d=2a__(2)
b= 2c
c= b/2____(3)
d-c = 30____(4)
putting value of (2) and (3) in 4
2a - (b/2) = 30
⇒4a -b = 60____(5)
now subtracting (1) and (5), we get, 
a = 19 years
b = 19-3 = 16 years
anji's age = 19 years
biji's age = 16 years
