The given table represents the production of different types of motorcycles (in thousands) over a period of six years. Study the table carefully and answer the question that follows.

What is the percentage increase in the total production of all types of motorcycles from 2014 to 2018?

$16 \frac{2}{3}$

Total production in 2014 = 84 + 87  + 89 + 100 = 360

Total production  in 2018 = 98 + 92 + 110 + 120 = 420

Required percentage  = \(\frac{420 - 360}{360}\) × 100

 = 16\(\frac{2}{3}\)
