Answer 1

Answer:

Step-by-step explanation:

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

Answer 2

age of ani and biju are respectively 19 & 16 yrs old
