Correct Answer: 7 : 22
Solution :
The average number of students studying science in the given years = $\frac{(78 + 69 + 83 + 55 + 65)}{5}$
= $\frac{350}{5}$ = 70
The total strength of students studying in the year 2022 = (76 + 65 + 48 + 31) = 220
$\therefore$ 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
Hence, the correct answer is 7 : 22.
