In a graduate class of 200, 40% are women and $$\frac{1}{5}$$ become lecturers. If the number of men who become lecturers is twice that of women, calculate approximate percentage of men who became lecturers.
A. 16%
B. 18%
C. 205
D. 27%
Answer: Option D
Solution(By Examveda Team)
Number of women = 40% of 200 = 80Number of men = 200 - 80 = 120
Number of women lectures = $$\frac{1}{5}$$ of 80 = 16
Number of men lectures = 16 × 2 = 32
∴ Required percentage :
$$\eqalign{ & = \left( {\frac{{32}}{{120}} \times 100} \right)\% \cr & = \frac{{80}}{3}\% \cr & = 26\frac{2}{3}\% \approx 27\% \cr} $$
