The total number of cars sold by company B during 2015, 2017 and 2018 is what percentage less than the total number of cars sold by company C in 2013, 2015, 2017 and 2018?
Answer & explanation
Correct answer: option 2
Total number of cars sold by company B during 2015, 2017 and 2018
= 60 + 53 + 67
= 180
Total number of cars sold by company C in 2013, 2015, 2017 and 2018
= 65 + 66 + 63 + 76
= 270
Required percentage = \(\frac{270 - 180}{270}\) × 100
= \(\frac{90}{270}\) × 100
= 33\(\frac{1}{3}\)
