Hi shahmughal,

I believe that this question has at least one typo in it. Based on the data involved, there should be more than 90 bedrooms in the building. What is the source of this question? And what were the answer choices that came with the original question?

A building has 60 apartments, out of which 2/5 have 1 bedroom and rest have 2 or 3 bedrooms.If there are 90 rooms in the building then how many 3 bedrooms in the building.

2/5 have 1 bedroom
2/5 of 60 = 24
So, 24 apartments have 1 bedroom.

This means the remaining 36 apartments have either 2 bedrooms or 3 bedrooms.

Then how many 3 bedrooms in the building?
All we know at this point is that 36 apartments have either 2 bedrooms or 3 bedrooms.
So, our answer is between 0 and 36

The answer choices that you provided don't make any sense since none of them are integers.

a. 2/3
b. 5/3
c. 7/14
d. 17/3
e. 19/2

You might want to go back and re-read the question.
By the way, what is the source of this question?

Cheers,
