The total number of candidates is 4062.

Given:-

Percentage of absent candidates = 5%

Percentage of failed candidates = 15%

Number of Candidates passed = 3250

To Find:-

The total number of candidates.

Solution:-

We can easily find the total number of candidates by using these simple steps.

As

Percentage of absent candidates = 5%

Percentage of failed candidates = 15%

Number of Candidates passed = 3250

Total percentage = 100%

Percentage of absent and failed candidates = 5 + 15 = 20%

Percentage of Passed candidates = Total candidates - Percentage of absent and failed candidates

Percentage of Passed candidates = 100 - 20

Percentage of Passed candidates = 80%

Now, As given

Number of passed candidates = 3250

and Let the total number of candidates be x.

Accordingly,

80\% \: of \: x = 3250

 \frac{80}{100}  \times x = 3250

x = 3250 \times  \frac{100}{80}

x = 3250 \times  \frac{10}{8}

x = 406.25 \times 10

x = 4062.5

Hence, The total number of candidates is 4062.
