Question

sum of Krishna's present age and square root of his present age is 30 years.He got married 3 years back. At that time his wife was 10/11 as old as he was. what is the present age of his wife?​

Answer 1

Answer:

23 years.

Step-by-step explanation:

Let the present age of Krishna be x.

x + √x = 30

By comparing it with 25 + √25 = 30

Which says that the present age of Krishna is 25.

Age of Krishna 3 years ago = 22

Age of his wife at that time (10/11)*22 = 10*2 = 20

Present age of his wife = 23 years.
