THE DECIMAL PART OF THE TWO POSITIVE NUMBERS ARE EQUAL. THE NUMBER OBTAINED BY SUBTRACTING THE FIRST FROM THE SECOND IS ?
A- ALWAYS A NATURAL NUMBER
B- ALWAYS AN INTEGER
C- ALWAYS A WHOLE NUMBER
D- NONE OF THE ABOVE

Answer :

We know whole numbers  :   1 , 2 , 3 , 4 , 5  , ...
And
Natural numbers  :   0 , 1  , 2 , 3 , 4 , 5  , ...
And
Integers :   .... , - 5 , - 4 , - 3 , - 2 , - 1 , 0 , 1  , 2 , 3 , 4 , 5  , ... 

And from given information  we can have our numbers , As :

first number  =  4 . 375 
And
Second number  = 2 . 375
So,
First number  - Second number   = 4 . 375  - 2 . 375 =  2

Or
first number  =  4 . 375 
And
Second number  = 5 . 375
So,
First number  - Second number   = 4 . 375  - 5 . 375 =  - 1

So,

Our number always a integer
