The average population of city B for all the given years is what percent less than the total population of city A for 2014, 2016 and 2018?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 62.
Total population of city B for all years = 48 + 50 + 55 + 60 + 65 + 64 = 342
Average population of city B for all years = 342/6 = 57
Total population of city A for 2014, 2016 and 2018 = 44 + 52 + 54 = 150
Required percentage = [(150 – 57) /150] × 100 = 62%
