Show answer & explanation
Correct answer: B
Concept
When a question asks for the difference between two combined totals, first add the specified entries within each group. Then subtract the smaller total from the larger total so that the difference is non-negative.
Application
Company A in 2016 and 2017: 180 + 230 = 410.
Company B in 2018 and 2020: 210 + 350 = 560.
Required difference: 560 − 410 = 150.
Cross-check
Adding the difference back to the smaller total gives 410 + 150 = 560, which matches the larger total. Therefore, the required difference is 150.
