1. One third of the faculty members of a department are female. Sixteen of the male teachers are unmarried while 60% of them are married. The total number of faculty members in the department is_____
- A. 72
- B. 72
- C. 72
- D. 72
Answer: Option B
Explanation:
মনে করি,
মোট faculty members = x জন
মহিলা faculty members x/3 জন
পুরুষ faculty members x - x/3 = 2x/3 জন
অবিবাহিত পুরুষের সংখ্যা = 2x/3 - 2x/5 জন
= 10x - 6x / 15 জন = 4x/15 জন
প্রশ্নমতে,
4x/15 = 16
x = 16 × 15 / 4
x = 60জন
