Question 54

The table shows the production of different types of cars (in thousands).

The average production of cars in 2018 is approximately what percent less than the total production of type D cars in 2015 and type B cars in 2017 taken together ?

Solution

From the table,

The average production of cars in 2018 = $$\frac{65+72+56+68+64}{5}$$ = $$\frac{325}{5}$$ = 65

The total production of type D cars in 2015 and type B cars in 2017 taken together = 56 + 64 = 120

$$\therefore\ $$Required percentage = $$\frac{120-65}{120}\times100$$

$$=\frac{55}{120}\times100$$

$$=\frac{550}{12}$$

$$=$$ 45.8%

Hence, the correct answer is Option C
