100 and 200 are the two hundreds on either side of 150. Both are an equal distance away. In those circumstances my recommendation is to round to the even - that is 200.
The general advice is to round 5s up but that advice is given by those who do not understand statistics and the introduction of bias.

200
150 and above = 200 but less than 150 = 100
To the nearest hundred it is zero.
To the nearest ten: 150 To the nearest tenth: 150.00
8 rounded to the nearest hundred is "zero".
