### HideShow timer Statistics

Currently people in the United States eat, on the average, 1,431 pounds of food per year, 35 pounds more than in 1980. This increase is, at least in part, because people between the ages of 15 and 64 have accounted for an increasing share of the population.
Which of the following can be properly inferred from the passage above?
(A) More than half of the current population of the United States is between the ages of 15 and 64.
(B) The population has risen since 1980.
(C) Children below the age of 15 require, on the average, more food than do people over the age of 64.
(D) Before 1980 children below the age of 15 outnumbered people between the ages of 15 and 64.
(E) Individuals between the ages of 15 and 64 consume, on the average, more food than do those younger or older.

I tried to use math equation X = N1X1+N2X2/(N1+N2) to explain this problem with no success. Could anyone help me with this question?

IMO A.

(A) More than half of the current population of the United States is between the ages of 15 and 64.
-- I guess POE would be the best to find the answer

(B) The population has risen since 1980.
-- this could be a conclusion NOT the inference
(C) Children below the age of 15 require, on the average, more food than do people over the age of 64.
-- too much to infer about the quantity of food consumption
(D) Before 1980 children below the age of 15 outnumbered people between the ages of 15 and 64.
-- no info about before 1980 population
(E) Individuals between the ages of 15 and 64 consume, on the average, more food than do those younger or older.
-- too much to infer about the quantity of food

More people between 15-64 accounted for the increase => E

I will go with E.

Evidence: Population between the age 15 and 64 increases
Conclusion: Per head consumption of food increases.

Inference: People between the age 15 and 64 consume more foods.

A is not flawless.

Mine: E

Thats seems to directly illustrate that since ppl b/w 15 and 64 have more food than those younger/older and as their population has increased the average has gone up too.
