Question

A balanced diet should contain 12% of proteins, 25% of fats, and 63% of carbohydrates. If a child needs 2600 calories in his food daily, find in calories the amount of carbohydrates in his daily food intake.

Answer 1

Hint: It is given that the total requirement of a child is 2600 calories and 63% of 2600 calories is the requirement of carbohydrates. Just open the percentage and solve it further.

Complete step-by-step answer:
According to the question, it is given that,
The required percentage of proteins in a balanced diet = 12%,
The required percentage of fats in a balanced diet = 25%,
The required percentage of carbohydrates in a balanced diet = 63%,
The total requirement of calories = 2600 calories.
Required calories of proteins = \[\dfrac{12}{100}\times 2600\]
On solving we get,
= 12 × 26
= 312 calories.
Required calories of fats = \[\dfrac{25}{100}\times 2600\]
On solving we get,
= 25 × 26 calories.
= 650 calories.
Required calories of carbohydrates = \[\dfrac{63}{100}\times 2600\]
On solving we get,
= 63 × 26 calories.
= 1638 calories.
Hence, the required amount of carbohydrates in daily food intake is 1638 calories.

Note: In this type of question, we might add all the calories and then conclude the answer which is wrong. We only need to find the calories of carbohydrates. So, after getting the calories of carbohydrates, conclude the answer.
