Thanks for your questions. your questions was –

What will be the result of [10] – [3], if it is given that [x] = -x2.

Correct answer: a

**Your question Explanation:**

According to the given in question, [x] = -x2.

Substituting the value of x as x=10 in this equation, we get, [10] = -100

Now, substituting the value of x as x=3 in this equation, we get, [3] = -9

Now, substituting these values in [10] – [3] = (-100) – (-9) = -100 + 9 = -91

Hence, the correct answer is option a.
