Answer:
1st One goes to the third one
2nd one goes to the 1st one
3rd one goes to the 4th one

Answer is 280
First, find A = 35% (100% less the three known percents = 35
Second, find ratio of B
20% of x = 160
Divide 160/.20 to isolate x
X=800 (total biscuits)
Now take A percentage x 800 biscuits
800 x 35% = 280 people chose biscuit A
