The quantity of fat in a kilogram of food A plus the quantity of protein in a kilogram
of food a is 100 g. The quantity of protein in a kilogram of food A minus twice the
quantity of fat in a kilogram of food A is 10 g. How many grams of protein are there in
a kilogram of food A?

Step-by-step explanation:
Energy requirements
Although, in principle, it would be desirable to determine the requirements of children, in the same way as for adults from measurements of energy expenditure, this approach involves many difficulties in practice. Information is indeed available on the BMRs of children of all ages for which prediction equations are given in Table 5. However, in young infants, in whom the requirement for growth is a substantial component of the total requirement for energy, there are large variations within the normal range, in the rate of growth, and probably also in the composition of the tissue laid down. Moreover, for both infants and children, it is not possible to specify with any confidence the allowance that should be made for a desirable level of physical activity. We have therefore followed the example of the 1971 Committee (la) and estimated the energy requirements from birth to 10 years from the observed intakes of healthy children growing normally.
6.3.1.1 Infants (birth to 12 months). Up to 6 months of age the 1971 Committee (la) used the results collected by Fomon et al. (55) for the intakes of infants fed breast milk by bottle. For older children, they used figures for the intakes of children in the United States of America and the United Kingdom presented by Leitch & Widdowson to the second FAO Committee on Calorie Requirements (56). A much larger collection of information is now available on the intakes of infants, children, and adolescents compiled from studies in Canada, Sweden, UK, and USA (57). Results from developing countries were not included in this analysis to ensure that the intakes represent those of groups of children who, on average, were growing along the 50th centile of the WHO reference standard. For the first 12 months there are some 4000 data points available. The means of the measured intakes at each month for the first year are given in Table 21. That table shows a fall in energy intake per kg of body weight between 3 and 6 months which is maintained until 9 months, and then rises again towards 1 year. We believe this reduction to be a real phenomenon, representing a period when the very high growth rate characteristic of the first 3 months of life has declined but is not yet balanced by increased physical activity.
