If [x] is the greatest integer less .....

this question is basically saying that the numbers in [ ] must be rounded, but only to the number either LESS than or EQUAL to the number in the [ ]. So, for example: [-1.6] is going to be rounded to [-2] because -2 is LESS than -1.6. [3.4] is going to be rounded to 3 since 3 is LESS THAN 3.4. Same goes for [2.7], it is going to be rounded to 2, since 2 is LESS than 2.7.


Thus,

-2 + 3 + 2 = 3


I hope this helps

solving such ques with the help of a number line can be very helpful





for [x], check the greatest intger that is less than or equal to x
[-1.6] = -2
[3.4] = 3
[2.7] = 2

Sum = 3

Option A

THANKS AGAIN ALL FOR YOUR INPUT!

IT MAKES PERFECT SENSE!!
