The Correct Option is B
Solution and Explanation
From the pie chart:
Chemistry = 23%
English = 27%
Biology = 12%
Total percentage = \( 23 + 27 + 12 = 62% \) Total number of teachers = 1800 \[ \text{Required number} = \frac{62}{100} \times 1800 = \boxed{1116} \]
Chemistry = 23%
English = 27%
Biology = 12%
Total percentage = \( 23 + 27 + 12 = 62% \) Total number of teachers = 1800 \[ \text{Required number} = \frac{62}{100} \times 1800 = \boxed{1116} \]
