Number of female members in health club E is what percent less than number of male members in health club B?

A) 56

$\frac{2}{3}$

B) 54

$\frac{1}{2}$

C) 60

$\frac{2}{3}$

D) 64

$\frac{1}{3}$

Option A

Number of male and female members in Health club E

= $\frac{12}{100}\times6300$ = 756

Number of male members in health club E

= $\frac{8}{100}\times2600$ = 288

Number of female members in health club E = 756 - 288=468

The number of male members in health club B

= $\frac{30}{100}\times3600$ = 1080

Required less percentage = $\frac{1080 - 468}{1080}\times100$

= 56 $\frac{2}{3}$
