Answer 1

Answer:

Step-by-step explanation:

virat's present age is 12 years and virat's father's present age is 36 years.

Solution:

It is given that,

virat's father's age is 3 times of her age.

Thus;

Let the present age of virat be x years

and the present age of her father's age be 3x years.

Also,

virat's age after 12 years will be ;

(x + 12) years.

And ,

virat's father's age after 12 years will be ; (3x + 12) years.

According to the question;

After 12 years virat's father is two times of her age.

ie;

=> 3x + 12 = 2(x + 12)

=> 3x + 12 = 2x + 24

=> 3x - 2x = 24 - 12

=> x = 12

Thus,

virat's present age

= x years

= 12 years

And,

virat s father's present age

= 3x years

= 3•12 years

= 36 years

Hence,

The present ages of virat  and her father are 12 years and 36 years respectively.
