Solution
Answer: Option D
Solution:
Number of lecturers in various subjects are:| Subject | Number of Males | Number of Females |
| Chemistry | 208 × = 26 | 208 - 26 = 182 |
| Education | 288 × = 180 | 288 - 180 = 108 |
| Hindi | 192 × = 48 | 192 - 48 = 144 |
| Mathematics | 336 × = 144 | 336 - 144 = 192 |
| Physics | 224 × = 144 | 224 - 144 = 80 |
| Zoology | 352 × = 154 | 352 - 154 = 198 |
\begin{aligned} & \text{Required %} \\ & = \left(\frac{192}{192+182}\times100\right)\% \\ & = \left(\frac{192}{374}\times100\right)\% \\ & = \frac{9600}{187}\% \\ & = 51.3\% \\ & \approx 51\% \\\end{aligned}
