Based on the data in the table, answer the questions that follow The following table presents the percentage (%) distribution of candidates who were enrolled for Ph.D. entrance exam and the candidates who passed the exam from seven different Institutes A - G. Total number of candidates enrolled were 17100 and candidates who passed the exam were 11400. Institute-wise Percentage (%) Distribution of Candidates Candidates → Institute ↓ Enrolled (%) (out of 17100) Passed (%) (out of 11400) A 16% 12% B 22% 18% C 15% 17% D 10% 13% E 17% 16% F 8% 9% G 12% 15%
What percentage of candidates passed the exam from Institute F, out of the total number of candidates enrolled in F?
75%
The question asks for the percentage of candidates who passed the Ph.D. entrance exam from Institute F, calculated with respect to the total number of candidates who were enrolled in Institute F.
We are given the following information:
Let's look at the data for Institute F from the table.
| Candidates → Institute ↓ |
Enrolled (%) (out of 17100) |
Passed (%) (out of 11400) |
|---|---|---|
| A | 16% | 12% |
| B | 22% | 18% |
| C | 15% | 17% |
| D | 10% | 13% |
| E | 17% | 16% |
| F | 8% | 9% |
| G | 12% | 15% |
From the table, for Institute F:
First, we need to calculate the actual number of candidates enrolled in Institute F:
Number of candidates enrolled in F = 8% of 17100
Number of candidates enrolled in F = $\frac{8}{100} \times 17100 = 8 \times 171 = 1368$
Next, we need to calculate the actual number of candidates who passed the exam from Institute F:
Number of candidates passed in F = 9% of 11400
Number of candidates passed in F = $\frac{9}{100} \times 11400 = 9 \times 114 = 1026$
The question asks for the percentage of candidates who passed from Institute F out of the total number of candidates enrolled in F. This means we need to calculate the pass percentage specifically for Institute F based on its own enrolled candidates.
Percentage of candidates passed in F out of total enrolled in F = $\left( \frac{\text{Number of candidates passed in F}}{\text{Number of candidates enrolled in F}} \right) \times 100\%$
Percentage = $\left( \frac{1026}{1368} \right) \times 100\%$
Now, let's simplify the fraction $\frac{1026}{1368}$. Both numbers are divisible by 2:
$\frac{1026 \div 2}{1368 \div 2} = \frac{513}{684}$
Both 513 and 684 are divisible by 9 (sum of digits 5+1+3=9, 6+8+4=18):
$\frac{513 \div 9}{684 \div 9} = \frac{57}{76}$
Both 57 and 76 are divisible by 19 (since $57 = 3 \times 19$ and $76 = 4 \times 19$):
$\frac{57 \div 19}{76 \div 19} = \frac{3}{4}$
So, the fraction is $\frac{3}{4}$. Now, calculate the percentage:
Percentage = $\frac{3}{4} \times 100\% = 0.75 \times 100\% = 75\%$
Therefore, 75% of the candidates enrolled in Institute F passed the exam.
Understanding the different percentages is key in data interpretation questions like this. Here's a quick summary of the calculations for Institute F:
Data interpretation questions often involve calculating different types of percentages or averages based on provided tables or charts. It's important to carefully read what the percentage is relative to (e.g., percentage of passed out of total enrolled, percentage passed out of enrolled in a specific institute, percentage distribution out of total passed). In this case, the key was to calculate the pass rate *within* Institute F.
Practice with different types of data representation (tables, bar graphs, pie charts) and percentage calculations will help you solve such problems efficiently.
