Question

a balanced diet contain 12% caloric intake from proteins 25% caloric intake from fats,and the rest from carbohydrates.if a certain person is prescribed 1300 calories per day find his caloric intake from each of these per day

Answer 1

Protein = 12%.
Fat = 25%.
Carbohydrate = 100-(25+12) = 63% from 1300 calories.
Protein = 1300*12/100 = 156 calories.
Fat = 1300*25/100 = 325 calories.
Carbohydrate = 1300*63/100 = 819 calories.

Answer 2

Concept

Percentage in mathematics is the number or ratio that can be expressed as a fraction of 100. For calculating percentage of a number divide the number by whole and multiply it with 100. Percentage in simple words means part per hundred.

Given

1) 12% calorie intake from protein

2) 25% calorie intake from fats

3) Rest from carbohydrates

4) Total calories per day = 1300

Find

Calorie intake from each of these per day

Solution

We are given that

Calorie intake from Protein = 12%

Calorie intake from Fat = 25%

Rest from carbohydrate = (100-(25+12))

= 63%

Total intake in a day = 1300 calories

Using the concept of Percentage

Protein = 1300*12/100 = 156 calories

Fat = 1300*25/100 = 325 calories

Carbohydrates = 1300*63/100 = 819 calories
