Question

7.  The present age of Sita’s father is three times the present age of Sita. After six years sum of their ages will be 69 years. Find their present ages.

Answer 1

Sita’s present age = x
Sita’s father present age = y

According to question,
y = 3x
and
(x + 6) + (y + 6) = 69
x + y = 69 - 12 = 57
x + 3x = 57
4x = 57
x = 57/4 = 14.25

y = 14.25 * 3 = 42.75

Sita’s present age is 14.25 years
Her father’s present age is 42.75 years

Answer 2

Answer:

let Sita was present age =x her father' s age be 3x

Step-by-step explanation:

• after 6 year Sita age X + 6
• her father's age 3 X + 6 according to question

X + 6 + 3 X + 6 is equal to 69

4 x + 12 is equal to 69

4 x is equal to 57

then x is equal to 14 .25

so sitas age is 14.25 and her father's age is 42 .75
