एक विश्वविद्यालय में 500 फैकल्टी मेंबर्स (केवल पुरुष और महिला) हैं, जिनमें से 60% महिलाएं हैं। महिलाओं की औसत लंबाई 162 cm और पुरुषों की औसत लंबाई 168 cm है।विश्वविद्यालय के फैकल्टी की औसत लंबाई (cm में) कितनी है?
Detailed Solution & Logic
164.4
Total faculty = 500
Female faculty = 60% of 500 = 300
Male faculty = 500 - 300 = 200
Average height =$ \frac{300 \times 162 + 200 \times 168}{500} $
$ = \frac{48600 + 33600}{500} $
$ = \frac{82200}{500} = 164.4 $
164.4 cm
