| Directions: Study the following pie chart carefully to answer the questions that follow. [IBPS (PO) 2012] |
| Percentagewise distribution of teachers who teach six different subjects |
 |
| Total number of teachers = 1800 |
| If two-ninth of the teachers who teach Physics, are female, then number of male Physics teachers is approximately what percent of the total number of teachers who teach Chemistry? |
A) 57%
B) 42%
C) 63%
D) 69%
E) 61%
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 \[=\frac{238}{414}\times 100\approx 57%\] |
