The total number of students in a school can't be 1650.70%.
But if your question mean:
The total number of students in a school is 1650.
70% of the pupils are boys.
How many girls are there in the school?
Then:
70% of the pupils are boys.
100 % - 70 % = 30 %
30% of the pupils are girls.
30 % = 30 / 100 = 0.3
0.3 * 1650 = 495
The total number of girls in a school is 495
