In a survey of 200 people, 20% of the men and 10% of the women are athletes. If 29 people are athletes in total, how many women were in the survey?
a) 29
b) 90
c) 100
d) 110
e) 200
We are given the following information
1. 20% of the men are athletes
2. 10% of the women are athletes
3. Total number of athletes is 29
Let the total number of women be x.
Therefore, the total number of men is 200-x
The equation formed is 0.2(200 - x) + 0.1x = 29
40 - 0.2x + 0.1x = 29 -> 0.1x = 11 -> x = 110
Therefore, the total number of women in the survey are
110(Option D)
