Answer 1

Correct Answer - Option 4 : 5 : 8

Calculation:

The number of candidates who qualified in bank A = 14/100 × 1500 = 210

The number of candidates who qualified in bank E = 28/100 × 1200 = 336

Ratio of the number of candidates who qualified in bank A to the number of candidates who qualified in bank E = 210/336 = 5/8

∴ Ratio of the number of candidates who qualified in bank A to the number of candidates who qualified in bank E is 5 : 8
