Download Solution PDFCalculation:
The average number of students studying science in the given years = (78 + 69 + 83 + 55 + 65)/5
⇒ 350/5 = 70
The total strength of students studying in the year 2022 = (76 + 65 + 48 + 31) = 220
Ratio of the average number of students studying science in the given years to the total strength of students studying in the year 2022 = 70 : 220
⇒ 7 : 22
∴ Option 1 is the correct answer.
