Question
Balanced diet should contain 12% of proteins, 25% of fats and 63% of carbohydrates. If a child needs 2600 calories in this food daily, find in calories the amount of each of these in his daily food intake.
Solution
In a balanced diet of 2600 calories, 12 % is protein.
∴ Amount of protein in food intake = 12 % of 2600
\[ = \frac{12}{100} \times 2600\]
\[ = 312\]
Similarly, a balanced diet contains 25 % fats.
∴ Amount of fats in food intake = 25 % of 2600
\[ = \frac{25}{100} \times 2600\]
\[ = 650\]
Similarly, a balanced diet contains 63 % carbohydrates.
∴ Amount of carbohydrates in food intake = 63 % of 2600
\[ = \frac{63}{100} \times 2600\]
\[ = 1638\]
