The hours between 2:00pm and 4:00pm is 2 hours. If originally 350 freshman and 200 sophomores are at the carnival, and 20 freshman leave every hour, we can determine how many freshman left in 2 hours:

$=20\cdot{2}=40$

and if 35 sophomores arrive every half our, we know that for every two hours there is 4 half hours, therefore:

$=35\cdot{4}=140$

The amount of freshman at 4:00pm:

$200-40=160$

and the amount of sophomores:

$200+140=340$

the ratio is 160:340
