Hi guys, could some of you quickly explain from what we can infer that the Set-Elements have to be integer?


Hi,
Given , the sets M and N contain exactly 'm and 'n' elements.

The number of elements is always a NON-NEGATIVE WHOLE NUMBER

We can't include 2.4 number of elements or 3.8 number of elements in a set.

Thanks, I get that. But from what do we infer that the actual elements have to be integer?

Hi,

It is asked in the question stem to find out the value of n(No of elements in set N), which is an integer.

We are not concerned whether the actual elements of the set(M/N) are integer or not.
