How many kilocalories of food energy does Rahim take in each day?

Think it through first, then pick an option.

  1. a 1725
  2. b 1350
  3. c 1225
  4. d 1100
Answer and explanation

Correct answer: c 1225

Carbohydrate 150 × 4 = 600, protein 100 × 4 = 400, fat 25 × 9 = 225. The total is 600 + 400 + 225 = 1225 kilocalories.

Why the other options are wrong

  • a 1725: 1725 needs fat to count as 500; 25 × 9 = 225, so the total is 1225.
  • b 1350: 1350 counts 125 too many; 600 + 400 + 225 = 1225.
  • d 1100: 1100 needs the fat share to be 100; 25 × 9 = 225, so the total is 1225.
