What is the ratio of the total production of type A cars in 2017 and type C cars in 2014 taken together to the total production of type B cars in 2014, type C cars in 2017, and type E cars in 2018 taken together?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 3 : 4
The total production of type A cars in 2017 = 66
The total production of type C cars in 2014 = 54
⇒ 66 + 54
⇒ 120
The total production of type B cars in 2014 = 46
The total production of type C cars in 2017 = 50
The total production of type E cars in 2018 = 64
⇒ 46 + 50 + 64
⇒ 160
⇒ 120/160
⇒ 3/4 or 3 : 4
