250 candidates appeared for an examination, out of which 225 passed. The percentage of the candidates who passed is:

Correct option is A

Given:

Total number of candidates = 250

Number of candidates who passed = 225

Formula Used:

$$\text{Percentage of candidates who passed} = \left( \frac{\text{Number of candidates who passed}}{\text{Total number of candidates}} \right) \times 100$$ 

Solution:

Substitute the values into the formula:

$$\text{Percentage of candidates who passed} = \left( \frac{\text{Number of candidates who passed}}{\text{Total number of candidates}} \right) \times 100$$ 

$$\text{Percentage of candidates who passed} = \left( \frac{225}{250} \right) \times 100$$ 

Percentage of candidates who passed = 0.9 × 100 = 90%

thus, the percentage of candidates who passed the examination is 90%.
