Accepted Answer

Step 1: Calculate total A-type cars produced from 2015 to 2017:
2015: 840
2016: 900
2017: 760
Total A = 840 + 900 + 760 = 2500 (thousands)

Step 2: Calculate total C-type cars produced from 2016 to 2018:
2016: 960
2017: 1000
2018: 1200
Total C = 960 + 1000 + 1200 = 3160 (thousands)

Step 3: Compare totals and find percentage difference:
Since total A (2500) is less than total C (3160), we find how much less it is.
Difference = 3160 - 2500 = 660

Percentage difference = (Difference / Total C) * 100 = (660 / 3160) * 100 ≈ 20.89%
Rounded off to nearest integer = 21%

Therefore, total A-type cars produced from 2015 to 2017 is 21% less than total C-type cars produced from 2016 to 2018.
