If |X| is the greatest integer less than or equal to X, what is the value of |-1.6|+|3.4|+|2.7|?

Could someone please explain how to get to the OA (A)?
Thanks

Consider|-1.6|

Now the integers less than -1.6 are -2, -3, -4,.............

Of these the greatest is -2.

So |-1.6|= -2

Consider |3.4|

Now the integers less than 3.4 are 3, 2, 1, 0, -1,..............

Of these the greatest is 3.

Hence |3.4|=3.

Similarly |2.7|=2

Hence the answer is -2+3+2=3
