The correct answer is, Yes, past age 85 years of age, for every 100 men, there are 200 women.

It is because of the fact that women are more in number than man above the age of 85 and this ratio is like 100 men per 200 women, which means the chances of getting a male friend is almost half after the age of 85. So women are more in number than men.
