The table shows the production of different types of cars (in thousands).
What is the ratio of the total production of cars of type A in 2014 and type C in 2013 taken together to the total production of cars of type B in 2016 and type E in 2015 taken together?
the total production of cars of type A in 2014 and type C in 2013 = 48 + 36 = 84
the total production of cars of type B in 2016 and type E in 2015 = 56 + 35 = 91
Ratio = $$\frac{84}{91} =Â \frac{12}{13} $$
So , the answer would be option a) 12:13.
