Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 164.4.
Female faculty = 0.60 × 750 = 450
Male faculty = 750 - 450 = 300
Total height from females = 450 × 162 = 72900 cm
Total height from males = 300 × 168 = 50400 cm
Average height = (72900 + 50400)/750 = 123300/750 = 164.4 cm
