Correct Answer - Option 3 : 1900

Given:

Candidates appearing in bank A = 1500

Candidates appearing in bank B = 2200

Candidates appearing in bank C = 3000

Candidates appearing in bank D = 980

Candidates appearing in bank E = 1200

Candidates appearing in bank F = 2500

Formula used:

Average = (sum of total observations)/ (numbers of observations)

Calculation:

From bank A numbers of candidates qualify for interview = 14% of 1500

⇒ (14 × 1500)/100

⇒ 210

From bank C numbers of candidates qualify for interview = 17% of 3000

⇒ (17 × 3000)/100

⇒ 510

From bank  numbers of candidates qualify for interview = 28% of 1200

⇒ (28 × 1200)/100

⇒ 336

The average number of candidates who appeared for the interview in bank A, C and E
together = (1500 + 3000 + 1200)/3

⇒ 5700/3

⇒ 1900

∴ The average number of candidates who appeared for the interview in bank A, C and E
together is 1900.
