Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 76 : 107.
Total Sales for Manufacturer Q = 280 + 290 + 310 + 310 + 330 = 1520 thousands
Total Sales for Manufacturer S = 400 + 420 + 430 + 440 + 450 = 2140 thousands
Required ratio = 1520 : 2140 = 76 : 107
Therefore, the ratio of manufacturer Q's total number of motorbike sales to the total number of motorbike sales of manufacturer S from 2016 to 2020 is 76 : 107.
