The pie chart presents the percentage contribution of different macronutrients to a typical 2,000 kcal diet of a person.
Figure Q.8 — macronutrient energy contribution
The typical energy density (kcal/g) of these macronutrients is given in the table.
The total fat (all three types), in grams, this person consumes is
Options:
(A) 44.4
(B) 77.8
(C) 100
(D) 3,600
Official Answer Key:
C
Step-by-Step Solution & Explanation
Step 1 — total fat share of energy. From the pie chart:
Unsaturated fat 20% + Saturated fat 20% + Trans fat 5% = 45%
Step 2 — energy from fat:
E_fat = 0.45 × 2000 = 900 kcal
Step 3 — convert energy to mass. All three fats have the same energy density, 9 kcal/g:
Mass = 900/9 = 100 g
Traps: (A) 44.4 uses only 20%; (D) 3,600 multiplies by 9 instead of dividing.
