Hi Yoong Liat
The word 'percents' is not used in reference to
a quantity per hundred. I attempted to give you a possible usage in which the meaning basically is "various or all sorts of different
quantities per hundred".
Oddly enough, the M-W Dictionary has an entry for "percents" with a notation that it is a British usage:
2 percents plural,
British : securities bearing a specified rate of interest
