Study the given pie-chart and answer the question that follows.
Percentage-wise distribution of teachers in six different subjects in a school is given in the pie-chart. The total number of teachers is 600. The ratio of male and female teachers is 3 : 1.
Find the ratio of teachers in Sanskrit and Hindi to teachers in Mathematics and Biology.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1 : 2.
Teachers in Sanskrit and Hindi = [(10/100) × 600] + [(10/100) × 600] = 60 + 60 = 120
Teachers in Mathematics and Biology = [(20/100) × 600] + [(20/100) × 600] = 120 + 120 = 240
Required ratio = 120 : 240 = 1 : 2
Therefore, the ratio of teachers in Sanskrit and Hindi to teachers in Mathematics and Biology is 1 : 2.
