By what percentage is the total production of type A motorcycles over six years, less than the total production of all types of motorcycles in 2013 and 2016?
Answer & explanation
Correct answer: option 4
Total production of A over all six years = 95 + 84 + 85 + 89 + 80 +98 = 531
Total production of all in 2013 and 2016 = ( 95 + 98 + 104 + 103 ) + ( 89 + 88 + 92 + 95 )
= 400 + 364
= 764
Required percentage = \(\frac{764 - 531 }{764}\) × 100
= 30.5%
