Answer: Option A
Solution(By Examveda Team)
Number of lecturers in various subjects are:$$\eqalign{ & \text{Chemistry → } \frac{13}{100}\times1600 = 208 \cr & \text{Education → } \frac{18}{100}\times1600 = 288 \cr & \text{Hindi → } \frac{12}{100}\times1600 = 192 \cr & \text{Mathematics → } \frac{21}{100}\times1600 = 336 \cr & \text{Physics → } \frac{14}{100}\times1600 = 224 \cr & \text{Zoology → } \frac{22}{100}\times1600 = 352 \cr} $$
Subject | Number of Males | Number of Females |
Chemistry | 208 × $$\frac{1}{8}$$ = 26 | 208 - 26 = 182 |
Education | 288 × $$\frac{5}{8}$$ = 180 | 288 - 180 = 108 |
Hindi | 192 × $$\frac{1}{4}$$ = 48 | 192 - 48 = 144 |
Mathematics | 336 × $$\frac{3}{7}$$ = 144 | 336 - 144 = 192 |
Physics | 224 × $$\frac{9}{14}$$ = 144 | 224 - 144 = 80 |
Zoology | 352 × $$\frac{7}{16}$$ = 154 | 352 - 154 = 198 |
Total number of male lecturers in the university
= 26 + 180 + 48 + 144 + 144 + 154
= 696
