The number of male members in health clubs A and C is approximately what percentage less than the number of members (both male and female) of health clubs B and C?
A69.42
B72.54
C51.37 ✓ Correct
D42.21
Correct answer: (C) 51.37
Explanation
The figure is about 51.37%, so the answer is 51.37.
Male members in A and C are 1512 plus 1368, which is 2880.
Members of clubs B and C are 4158 plus 1764, which is 5922.
The difference is 5922 minus 2880, which is 3042.
The percentage less is 3042 divided by 5922 times 100.
This works out to about 51.37%.
The comparison uses the larger group, the members of B and C, as the base.
