Which of the following diets would supply the most grams of protein?

(A) 500 grams of A

(B) 250 grams of B

(C) 350 grams of C

(D) 150 grams of A and 200 grams of B

(E) 200 grams of B and 200 grams of C

The most grams of protein will come from the highest percentage(s) of the highest absolute amount(s).

Based on amounts and percentages, at a glance, the answer should be (E)

Closest is C. But 20 percent of 350 (C), is less than 20 percent of 400 (E).

The answer is E. I decided to check the others.

Multiplying percentages by amounts is quick, under a minute.

Diet A = (.10) protein

Diet B = (.20) protein

Diet C = (.20) protein

Options by answer, in grams of protein:

(.10)(500) = 50

(Answer A, 500g of A)

(.20)(250) = 50

--10% is [25], doubled = 20% = 50

(Answer B, 250g of B)

(.20)(350) = 70

--10% is [35], doubled = 20% = 70

(Answer C, 350g of C)

(.10)(150) + (.20)(200) =

(15 + 40) = 65

(Answer D, 150g of A + 200g of B)

(.20)(200) + (.20)(200) =

(40 + 40) = 80

(Answer E, 200g of B + 200g of C)80 grams of protein is the most

Answer E
