What is the average number of female members in health clubs C, D and E ?
Correct Answer: Description for Correct answer:
The number of members (both male and female) in health club C
= \( 4200 \times \frac{35}{100} = 1470\)
The number of male members in health club C = \( 2400 \times \frac{33}{100} = 792 \)
The number of female member in health club C = \( 1470 - 792 = 678 \)
The number of members (both male and female) in health club D
= \( 4200 \times \frac{15}{100} = 630\)
The number of male members in health club D = \( 2400 \times \frac{12}{100} = 288 \)
The number of female member in health club D = \( 630 - 288 = 342 \)
The number of members (both male and female) in health club E
= \( 4200 \times \frac{8}{100} = 336\)
The number of male members in health club E = \( 2400 \times \frac{10}{100} = 240 \)
The number of female member in health club E = \( 336 - 240 = 96 \)
Required average = \( \frac{678+342+96}{3} = \frac{1116}{3} = 372 \)
