| Directions: Study the two figures given below and answer the five questions that follow. |
 |
 |
| If the number of female Physics professors in the age group 25-34 equals 25% of all the Physics professors in that age group, then what is the number of male Physics professors in the age group 25-34? |
A) 9
B) 6
C) 3
D) 2
Correct Answer: A
Solution :
| Total number of Physics professors is 40, from fig. A. From fig. B, the percentage of Physics professors in the age group 25-34 is 30% |
| Hence, total number of Physics professors in the 25-34 range \[=40\times \frac{30}{100}=12\] |
| Out of these 12, 25% i.e.\[\left( \frac{25}{100} \right)\times 12\]are female. |
| Hence, the number of male Physics professors in the age group 25-34 |
| \[=12-\frac{12\times 25}{100}\] |
| \[=12-3=9\] |
