Question

Six years ago, the respective ratio between the ages of sia and her father that time was 1 : 7. The difference between the age of sia's father and sia is 36 yr. What will be sia's age 5 yr from now?

Answer 1

Answer: After 5 yrs from now, Sia's age would be 17 yrs.

Step-by-step explanation:

Given that,

The ratio of age of Sia and her father 6 years ago= 1:7

Suppose,

Sia's age be x and her father's age be 7x.

Since the difference between their ages is 36, So we have

7x-x=36

6x=36

x=6

6 years ago, Sia's age would be 6 yrs.

So, the present age of Sia would be 12 yrs.

But we need to find sia's age after 5 yrs from now, So we need to add 5 yrs more.

Sia's age after 5 yrs from now= 12+5= 17 yrs.
