A.
500
B.
550
C.
600
D.

Correct Answer
A. 500
Explanation The number 527, when rounded off to the nearest 100, would be 500. This is because 527 is closer to 500 than it is to 600. When rounding to the nearest 100, any number that is 50 or above is rounded up to the next hundred, and any number below 50 is rounded down to the previous hundred. In this case, 527 is closer to 500 than it is to 600, so it is rounded down to 500.
