B) 45 years
C) 54 years
D) 55 years​

Answer 1

Answer:-

Your Answer is option B) 45 years.

Explanation:-

Given:-

• Present age of Anisha is a multiple of 9.

• Last year i.e previous year her age was multiple of 11.

• Her age is between 30 years and 60 years.

To Find:-

• The present age of Anisha.

So Now,

Since the present age of Anisha is multiple of 9 and lies between 30 and 60 years, so there are three ages possible,

• 36 years.
• 45 yesrs and,
• 54 years.

And 1 year before her age was multiple of 11.

Also multiples of 11 between 30 and 60 are,

• 33 years.
• 44 years and,
• 55 years.

Now,

The above ages which are multiple of 11 are the possible ages of last year so the Difference between the present age and the age before one year should be equal to 1.

Case I:-

• Present age = 36.
• Age in last year = 33.

↦ 36 - 33 = 3 wich is not equal to 1.

So these are not the correct ages.

Case II:-

• Present age = 45.
• Age in last year = 44.

↦ 45 - 44 = 1.

So these may be the correct ages.

Case III:-

• Present age = 54.
• Age in last year = 55.

↦ 55 - 54 = -1 which is not equal to 1.

So these are not correct ages.

Therefore,

• The correct present age of Anisha is 45 years.
