Question 1061439: There are 10% more students in the freshman class than in the sophomore class. Combined there are 630 students in both classes. How many sophomores are there? Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let n be the size of the sophomore class. Then 100% of n + 110% of n=630. So:
n+1.1n=630
2.1n=630
n=300
There are 300 in the sophomore class; and 330 freshman. ☺☺☺☺
