Question

Sita is 6 years older than her friend Ashish. Sita's father is twice as old as Sita and Ashish is twice as old as his sister. The age of Sita's father is 39 years more than the age of Ashish's sister. Find the ages of Sita and Ashish.

Answer 1

ashish age is 13 years and 5 months
sita age is 19 years and 5 months

Answer 2

Let the present age of Sita be x
Let the present age of Ashish be y
As per the given condition,
x = y+6
As per the second condition,
x+39=y.
Substitution y=x+39 in eq.1
x= x+39+6
x-x =45
x=45+x
Substitution x=y+6
y+6=45+x
y-x = 41
