Answer:
Option D
Explanation:
Number of lecturers in various subjects are:
Chemistry → $\left(\frac{13}{100}\times1600\right)$ = 208
Education → $\left(\frac{18}{100}\times1600\right)$ = 288
Hindi → $\left(\frac{12}{100}\times1600\right)$ = 192
Mathematics → $\left(\frac{21}{100}\times1600\right)$ = 336
Physics → $\left(\frac{14}{100}\times1600\right)$ = 224
Zoology → $\left(\frac{22}{100}\times1600\right)$ = 352

Chemistry
|
$\left(\frac{1}{8}\times208\right)$ = 26
|
(208-26) = 182
|
Education
|
$\left(\frac{5}{8}\times288\right)$ = 180
|
(288-180) = 108
|
Hindi
|
$\left(\frac{1}{4}\times192\right)$ = 48
|
(192-48) = 144
|
Mathematics
|
$\left(\frac{3}{7}\times336\right)$ = 144
|
(336-144) = 192
|
Physics
|
$\left(\frac{9}{14}\times224\right)$ = 144
|
(224-144) = 80
|
Zoology
|
$\left(\frac{7}{16}\times352\right)$ = 154
|
(352-154) = 198
|
Required % = $\left\{\frac{192}{192+182}\times100\right\}$%
= $\frac{9600}{187}$ % = 51.3% = 51%.
