How many more television sets were sold by all the showrooms in the year 2017 than in 2019?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 34.
Total sales of each showroom in 2017 = 180 + 274 + 269 + 98 + 370 + 195 = 1386
Total sales of each showroom in 2019: 264 + 107 + 237 + 225 + 282 + 237 = 1352
Difference = 1386 - 1352 = 34
Therefore, the showrooms sold 34 more television sets in 2017 compared to 2019.
