Philoid · Accepted Answer

Given: Average score of the candidates of all four school is 66

Concept Used:

Explanation:

Let no. of students appeared from school III = x

Given, Average score of all schools = 66

10340 + 55x = 66x + 9768

10340 – 9768 = 66x – 55x

11x = 572

x

= 52

Therefore, no. of candidates appeared from school (III) is 52.
