Sita is 6 years older than her friend Asish. 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 Asish, s sister. Find the age of sita and asish

Answer 1

Hii friend.....
Let the Sita's age = x years
Let the ashish age = x - 6
Sita's father age = 2x
Ashish sister age = x-6/2

A.T.S
x-6/2+39=2x
x-6+78 = 4x
72 = 4x-x
72 = 3x
x= 24
So,Sita age = 24years
Ashish age = 24-6
18 years
THANKS
HOPE IT HELPS U☆☆☆

Answer 2

Let Ashish's sister's age be x yrs
Then,Ashish's age will be 2x yrs
Sita's age " (6+2x)yrs
Sita's father's age " 2(6+2x )yrs
Also,given that Sita's father's age is 39 more than age of Ashish's sister's.
Therefore, (x+39)=2(6+2x)
=> x+39=12+4x
=> 39-12=4x-x
=> 27=3x
=> 27/3=x
=> x=9

Ashish's age = 2x= 2×9=18yrs
Sita's age= 6+2x= 6+2×9=24yrs
