A) 69

B) 51.36

C) 72

D) 42.21

Answer:

Option B

Explanation:

Number of male members in health clubs A and C

Number of male and female members in health clubs B and C

= 6300×47% = 2961

Number of male members in health club A and C percent less than the number of both male and female members of health club B and C = $\frac{2961-1440}{2961}\times100$ = 51.36%
