In a graduate class of 200, 40% are women and 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.

Answer: Option D

Number of women = 40% of 200 = 80
Number of men = 200 - 80 = 120
Number of women lectures = $$\frac{1}{5}$$ of 80 = 16
Number of men lectures = 16 × 2 = 32
∴ Required percentage :
$$\begin{array}{rl}& =\left(\frac{32}{120}\times 100\right)\%\\ & =\frac{80}{3}\%\\ & =26\frac{2}{3}\%\approx 27\%\end{array}$$
