What is the ratio of the total production of type C cars in 2015 and type D cars in 2017 taken together to the total production of type B cars in 2016 and type A cars in 2017 taken together?

As per the given data in the question,

Total production of type C car in 2015=53

Total production of type D car in 2017=67

Hence total produce of the car of type C and D in the required year $$=53+67=120$$

Total production of type B car in 2016 =47

Total production of type A car in 2017 =43

Hence total produce of the car of type A and B in the required year$$=47+43=90$$

Hence, the required ratio $$=\dfrac{120}{90}=\dfrac{4}{3}$$
