Correct Answer 3036
Given:
|
Bank |
Candidates Appearing |
% of Candidates Qualifying |
|
I |
2200 |
26 |
|
J |
3000 |
17 |
Calculation:
|
Bank |
Candidates Appearing |
% of Candidates Qualifying |
Number of candidates |
Number of candidates who did not qualify |
|
I |
2200 |
26 |
2200 × 26% = 572 |
2200 - 572 = 1628 |
|
J |
3000 |
17 |
3000 × 17% = 510 |
3000 - 510 = 2490 |
Number of candidates who did not qualify in banks I and J together = 1628 + 2490 = 4118
Number of candidates who qualified in banks I and J together = 572 + 510 = 1082
Required difference = 4118 - 1082 = 3036
∴ Required difference is 3036.
