36% of the pupils in class 2 are boys the remaining 16 are girls how many pupils are in class 2?

This means 100% - 36% = 64% of the class are girls. And if the class size is s, then we have:
64% of s = 16

Or, written as a decimal:
0.64s = 16

To solve this equation for s, we type it into our search engine and we get:
s = 25
