The ages of two friends Anil and Biju differ by 3 years. Anil's father Dharam is twice as old as Anil and Biju is twice as old as his sister Cathy. The ages of Cathy and Dharam differ by 30 years. find the ages of Anil and Biju.

Answer 1

hey here is your answer

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
