The largest increase in turnover since last year is in Shift B with 6.4%.
How to calculate group has largest increase in turnovers?
To determine the shift with the largest increase in turnover since last year, we will calculate the year-to-year turnover percentage change for each shift by subtracting last year's turnover percentage from this year's turnover percentage.
Shift of turnover = Turnover percentage this year - Turnover percentage last year
Shift A = 16.8% - 16.2% = 0.6%
Shift B = 17.5% - 11.1% = 6.4%
Shift C = 14.5% - 9.8% = 4.7%
Shift D = 8.9% - 10.3% = -1.4%.
Therefore, the Option B is correct.
