9 x 5700 | x 100 | |
% = 75%. |
| 8% of 8550 | 8% of 8550 |
2.
Which institute has the highest percentage of candidates passed to the candidates enrolled?

The percentage of candidates passed to candidates enrolled can be determined for each institute as under:
| (i) P = |  |
|
18% of 5700 | |
x 100 | ![]](/_files/images/data-interpretation/common/15-sym-cbracket-h1.gif) |
% = | |
18 x 5700 | x 100 | |
% = 54.55%. |
| 22% of 8550 | 22 x 8550 |
| (ii) Q = | |
|
17% of 5700 | |
x 100 | |
% | = 75.56%. |
| 15% of 8550 |
| (iii) R = | |
|
13% of 5700 | |
x 100 | |
% | = 86.67%. |
| 10% of 8550 |
| (iv) S = | |
|
16% of 5700 | |
x 100 | |
% | = 62.75%. |

| 16% of 8550 |
Highest of these is 86.67% corresponding to institute R.
3.
The number of candidates passed from institutes S and P together exceeds the number of candidates enrolled from institutes T and R together by:
Answer: Option
Explanation:
| Required difference | = [(16% + 18%) of 5700] - [(8% + 10%) of 8550] |
| = [(34% of 5700) - (18% of 8550)] | |
| = (1938 - 1539) | |
| = 399. |
