\(\lfloor x \rfloor =\) the largest integer less than or equal to \(x\)
Qt A :: \(\lfloor -1.5 \rfloor\) \(= -2\)
Qt B :: \( - \lfloor 1.5 \rfloor\) \(= -1\)
Qt B > Qt A
Answer B
Qt A :: \(\lfloor -1.5 \rfloor\) \(= -2\)
Qt B :: \( - \lfloor 1.5 \rfloor\) \(= -1\)
Qt B > Qt A

The simplest way is to form a number line
Quantity A
-1.5 lies between -2 and -1
It says largest integer less than or equal to x, which means integer which is just left to -1.5, which is -2
Quantity B
1.5 lies between 1 and 2
It says largest integer less than or equal to x, which means integer which is just left to 1.5, which is 1
The whole thing is negative so Quantity B is -1
Hence, Answer is B
Quantity A
-1.5 lies between -2 and -1
It says largest integer less than or equal to x, which means integer which is just left to -1.5, which is -2
Quantity B
1.5 lies between 1 and 2
It says largest integer less than or equal to x, which means integer which is just left to 1.5, which is 1
The whole thing is negative so Quantity B is -1
Hence, Answer is B
