The correct Answer is:
To find the pass percentage of candidates who appeared for the examination, we can follow these steps: ### Step 1: Identify the total number of candidates and the number of candidates who passed. - Total candidates = 270 - Candidates who passed = 252 ### Step 2: Use the formula for pass percentage. The formula for calculating the pass percentage is: \[ \text{Pass Percentage} = \left( \frac{\text{Number of Candidates Passed}}{\text{Total Number of Candidates}} \right) \times 100 \] ### Step 3: Substitute the values into the formula. Substituting the values we have: \[ \text{Pass Percentage} = \left( \frac{252}{270} \right) \times 100 \] ### Step 4: Simplify the fraction. To simplify \(\frac{252}{270}\): - Both numerator and denominator can be divided by 9. \[ \frac{252 \div 9}{270 \div 9} = \frac{28}{30} \] ### Step 5: Further simplify the fraction. Now, simplify \(\frac{28}{30}\): - Both numerator and denominator can be divided by 2. \[ \frac{28 \div 2}{30 \div 2} = \frac{14}{15} \] ### Step 6: Calculate the percentage. Now, we can calculate the percentage: \[ \text{Pass Percentage} = \left( \frac{14}{15} \right) \times 100 \] Calculating this gives: \[ \frac{14 \times 100}{15} = \frac{1400}{15} = 93.33 \] ### Step 7: Convert to mixed number. To express 93.33 as a mixed number: - 93.33 can be written as \(93 \frac{1}{3}\). ### Final Answer: The pass percentage is \(93 \frac{1}{3}\%\). ---
