We can "logic" this one out, but it makes things a lot easier if we know that hecto is the metric prefix for 100. See here.

However, we know that hecto IS a metric prefix, so it must be some multiple of 10. Thus the pharmacist has 2*10^n + 55 grams, where n is some integer. The only number of that form is answer C, 255.

yes he has 255 grams of pills but each pill is 1 gram and 2 centigrams so how many pills does the pharmacist have?
