Question 14144
2 medium eggs + 3 cups Ice cream = 701 mg. Cholesterol

2 medium eggs + 2 cups Ice Cream = 650 mg. Cholesterol

_______________________________________________________

0             +  1 cup Ice Cream = (701 - 650) - 51 mg. Cholesterol

Now, substitute the value of 1 cup of Ice cream in the follwoing formula :

       1 medium egg + 1 cup of Ice Cream = 325 mg. Cholesterol
so,
        1 medium egg +  51 mg. cholesterol = 325 mg. Cholesterol 

so      1 medium egg = 325 - 51 mg. Cholesterol
          
         1 medium egg = 274 mg. Cholesterol

Thus  1 cup of Ice Cream = 51 mg. Cholesterol &
       1 medium egg = 274 mg. Cholesterol
