The table shows the production of different types of cars by a company (in thousands) in 5 years.
The average production of type D cars in 5 years is what percent less than the production of type E cars in 2018? (Correct to one decimal place)
As per the given given data in the question,
The average production of type D car $$\dfrac{46+50+54+67+68}{5}=57$$ thousand
Production of type E car in 2018 $$=70$$
Hence the required percentage $$=\dfrac{(70-57)\times 100}{70}=\dfrac{13\times 100}{70}=18.6\%$$
