 |
| Only 50% of the members (both male and female) in health club E have lifetime membership. If the number of females in health club E who have lifetime membership is 44, then what percent of male members in health club E have lifetime membership? |
A) \[48\frac{2}{3}\]%
B) \[54\frac{1}{3}\]%
C) \[57\frac{1}{34}\]%
D) \[51\frac{2}{3}\]%
E) \[60\frac{1}{3}\]%
Correct Answer: D
Solution :
| Total member of \[E=4200\times \frac{8}{100}=336\] |
| \[\therefore \]Number of members with lifetime membership |
| \[=\frac{336}{2}=168\] |
| \[\therefore \]Number of mates with lifetime membership |
| \[=168-44=124\] |
| Total number of males in, \[E=2400\times \frac{10}{100}=240\] |
| \[\therefore \]Required percentage \[=\frac{124}{240}\times 100=51\frac{2}{3}\]% |
