Answer:
Option A
Explanation:
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$\frac{2}{3}$
