What is the average number of appearing candidates in the screening test from all four states in the year 2021?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 3950.
The number of appearing candidates in the screening test from all four states in the year 2021 = (2900 + 4700 + 3400 + 4800) = 15800
Average = Sum of the observations/Total observations
Average = 15800/4 = 3950
