Answer:
Correct Answer: A
Solution:
- Number of teachers in Physics $ =1800\times \frac{17}{100}=306 $ Female teachers in Physics $ =306\times \frac{2}{9}=68 $ Male teachers in Physics $ =306-68=238 $ Number of teachers in Chemistry $ =1800\times \frac{23}{100}=414 $
$ \therefore $ Required percentage $ =\frac{238}{414}\times 100\approx 57% $
