Question 68
The table shows the production of different types of cars (in thousands).
The ratio of the total production of type A cars in 2017 and type D cars in 2015 to the total production of type B and type E cars in 2013 is:
Solution
The ratio of the total production of type A cars in 2017 and type D cars in 2015 = $$64+56$$ = $$120$$
the total production of type B and type E cars in 2013 = $$47+43$$ = $$90$$
hence $$\frac{2017(typeA )+(2015 type D)}{2013typeB + 2013 type E}$$
= $$\frac{64 + 56}{47 + 43}$$
= $$\frac{120}{90}$$
= by simplifying we get $$4:3$$
