We can use basic math to solve this problem. If nearly all of your grandmother's friends are women, we can assume that there are very few men in her age group. Let's use the answer choices to help us calculate an estimated number of women in her age group.

If we choose answer choice D), that means your grandmother has 113 friends who are women. But this would mean that there are only 226 people in her age group (since she remarked that it is rare to see a man over age 85). It is highly unlikely that an 87-year-old woman only has 226 peers in her age group.

If we choose answer choice A), that means your grandmother has 678 friends who are women. If we assume that she has roughly the same amount of male friends, that would mean there are around 1,356 people in her age group (including men and women). This seems like a more realistic number of people in her age group.

If we choose answer choice B), that means your grandmother has 452 friends who are women. But once again, this would mean there are only around 904 people in her age group (if we assume a similar number of men). This seems too low.

Therefore, the best choice is C) 226 women is too low, A) 678 women seems like a more reasonable number of people in her age group.
