Question

the present of Sita's father is three times the present age of Sita .after 6 years the sum of their age will be 69 years. find their present age.

Answer 1

let the present age of sita be X
so its father age is 3X
now after 6 years sita age is 6+X
and her father age is 3X+6

and ATQ
(3X+6)+(6+X)=69
=4X+12=69
=4X=57
=X=57/4

so the present age of sita is 57/4 years and her father age is 3×57/4=171/4

Answer 2

Step-by-step explanation:

Let the present age of Sita be 'x' years.

Then, her father's age = 3 * Times of sita

                                     = 3x.

6 years hence:

Sita age = x + 6.

Sita's father age = 3x + 6.

Sum of their ages will be 69.

⇒ x + 6 + 3x + 6 = 69

⇒ 4x + 12 = 69

⇒ 4x = 57

⇒ x = 57/4 (or) 14 (1/4) years.

Now,

3x = 3(57/4)

    = 171/4 (or) 42 (3/4) years.

Therefore:

∴ Age of Sita = 57/4 years (or) 14 (1/4) years.

∴ Age of Sita's father = 171/4 years (or) 42 (3/4) years.

Hope this helps!
