Question

Меню в режиме питания подростков по калорийности должно быть составлено так , чтобы ужин составлял 20% дневного рациона , обед-в 2 раза больше, чем ужин, остальное-завтраки. Причём первый завтрак должен составлять 25% дневного рациона питания. Найдите процентное отношение калорийности первого и второго завтрака.

Answer 1

Пусть дневной рацион 1, тогда 1ый завтрак:1/4, ужин 1/5, обед 2/5 тогда 2ой завтрак 1-1/4-3/5=2/5-1/4=(8-5)/20=3/20 или 15% от дневного рациона, тогда 3/20:1/4=12/20=3/5 т.е. 60% 2ой завтрак составляет от 1ого.

Answer 2

Всего 100% ужин-20% 2*20%=40% -обед 100%-(20%+40%)=40% - завтраки 25%- 1-й завтрак 40%-25%=15% -2-й завтрак

Answer 3

Menu Composition for Teenagers' Caloric Intake

To create a menu in accordance with the given requirements, where dinner constitutes 20% of the daily caloric intake, lunch is twice the size of dinner, and the remaining calories are allocated to breakfasts, we need to calculate the percentage of calories for the first and second breakfasts.

To begin, let's assume the total daily caloric intake is 100%.

According to the given information, dinner should constitute 20% of the daily caloric intake. Therefore, dinner will be 20% of 100%, which is 20%.

Next, lunch should be twice the size of dinner. So, lunch will be 2 times the size of dinner, which is 2 * 20% = 40%.

The remaining calories will be allocated to breakfasts. Since the first breakfast should constitute 25% of the daily caloric intake, we subtract the percentages of dinner and lunch from 100% to find the percentage remaining for breakfasts.

100% - 20% - 40% = 40%.

Now, we can calculate the percentage of calories for the first and second breakfasts. Since the first breakfast should constitute 25% of the daily caloric intake, we multiply the percentage remaining for breakfasts by 25% to find the percentage for the first breakfast.

40% * 25% = 10%.

The second breakfast will be the remaining percentage of calories for breakfasts, which is 40% - 10% = 30%.

Therefore, the percentage of calories for the first and second breakfasts is 10% and 30%, respectively.

Please note that the above calculations are based on the given information and do not take into account individual dietary needs or specific nutritional guidelines. It is always recommended to consult with a healthcare professional or nutritionist for personalized dietary advice.
