Q. A person is on a diet that consists of 50% carbohydrates, 30% fats, and 20% proteins. If they consume 1800 calories, how many calories are from carbohydrates?
A.
600 calories
B.
700 calories
C.
800 calories
D.
900 calories
Solution
50% of 1800 calories = 0.50 * 1800 = 900 calories from carbohydrates.
Q. A person needs 2000 calories a day and wants to get 15% of their calories from fats. How many grams of fat should they consume (1 gram of fat = 9 calories)? (2000)
A.
33 grams
B.
40 grams
C.
50 grams
D.
60 grams
Solution
15% of 2000 calories = 0.15 * 2000 = 300 calories from fats. 300 calories / 9 calories per gram = 33.33 grams, rounded to 33 grams.

B.
23.5°
C.
66.5°
D.
90°
