Analysis of the question
- Total number of candidates = 120
- Average marks of all candidates = 35
- Average marks of passed candidates = 39
- Average marks of failed candidates = 15

Solution

Step 1: Calculate the total marks obtained by all candidates
Total marks = Average marks * Total number of candidates
Total marks = 35 * 120
Total marks = 4200

Step 2: Calculate the total marks obtained by passed candidates and failed candidates
Let the number of passed candidates be x and failed candidates be y.
Total marks obtained by passed candidates = 39x
Total marks obtained by failed candidates = 15y
Total marks = Total marks obtained by passed candidates + Total marks obtained by failed candidates
4200 = 39x + 15y

Step 3: Form equation to find the number of passed candidates
We know that the total number of candidates is 120.
Therefore, x + y = 120
y = 120 - x
Substitute the value of y in the equation obtained in step 2.
4200 = 39x + 15(120 - x)
4200 = 39x + 1800 - 15x
4200 = 24x + 1800
24x = 2400
x = 100
Hence, the number of candidates who passed the examination is 100.
