Answer & Solution
Answer: Option A
Solution:
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
