Team Careers360 · Accepted Answer

Correct Answer: 80

Solution :
The average marks of the passed candidates are 35 and those of the failed candidates are 10.
Using the alligation method, we get,
The ratio of the number of pass students to fail students = 20 : 5 = 4 : 1
So, Total students = 4 + 1 = 5 units
According to the question, 5 units = 100
⇒ 1 unit = 20
Passed candidate = 4 units = 4 × 20 = 80
Hence, the correct answer is 80.
