Answer 2

Given,

Anisha's present age is a multiple of 9.

And, her last year's age is a multiple of 11.

To find,

The present age of Anisha in years.

Solution,

There is no such method to mathematically calculate and solve this mathematical problem. So, we will manually try and verify the ages.

Now, the previous age is a multiple of 11. So, the ages can be 11 or 22 or 33 ....or 99. (11-99 group of multiples of 11 and 121 is not a normal age,so upper limit is 99.)

Now, we have to see that which next age is divisible by 9

For 11, next age is 12 which is not divisible by 9.

For 22, the next age is 23 which is not divisible by 9.

For 33, the next age is 34 which is not divisible by 9.

For 44, the next age is 45 which is divisible by 9.

(45÷9 = 5)

Hence,the present age of Anisha is 45 years.
