Study the following pie chart that shows the percentage-wise distribution of teachers who teach six different subjects, and answer the question given below. Total number of teachers = 1600 If \(\frac{3}{8}\) of the teachers who teach Chemistry are females, then the number of male Chemistry teachers is what percentage of the total number of teachers who teach Mathematics? Correct Answer 45%

Subjects Number of teachers
Mathematics 25% of 1600 = 400
Physics 18% of 1600 = 288
Chemistry 18% of 1600 = 288
Economics 16% of 1600 = 256
Accountancy 8% of 1600 = 128
Biology 15% of 1600 = 240
 
 

 

Number of male chemistry teachers = 288 -

⇒ 288 - 108

⇒ 180

Required percentage = (180/400) × 100

⇒ 45%

∴ The number of male Chemistry teachers is 45% of the total number of teachers who teach Mathematics.
