Number of candidates appeared in the interview for the post of PO in a bank from five different states of India. The number of candidates who appeared in 2015 from MP is approximately what percentage of the total number of candidates appeared from MP for all the years taken together?

Correct option is A

Given:
Number of candidates from MP in 2015 = 400
Number of candidates from MP for all years:
2012: 250
2013: 280
2014: 240
2015: 400
2016: 540
Concept Used:
​$$\text{Percentage} = \left( \frac{\text{Number of candidates in 2015 from MP}}{\text{Total number of candidates from MP for all years}} \right) \times 100$$​
Solution:
 Total number of candidates from MP for all years:
250 + 280 + 240 + 400 + 540 = 1710
​$$\text{Percentage} = \left( \frac{400}{1710} \right) \times 100 \approx 23\%$$

Option (A) is right.
