Correct answer: C
Concept
To compare totals from two groups, first add every component within each group.
Then write the first total to the second total as a ratio and divide both terms by their greatest common divisor.
Application
Total employees in 2018 = 290 + 176 + 222 + 240 + 280 + 272 = 1480.
Total employees in 2019 = 256 + 152 + 240 + 224 + 304 + 264 = 1440.
Required ratio (2018 : 2019) = 1480 : 1440.
The greatest common divisor of 1480 and 1440 is 40, so dividing both terms by 40 gives 37 : 36.
Cross-check
Multiplying 37 and 36 by 40 reproduces 1480 and 1440 respectively. Therefore, the required ratio is 37 : 36.
