A table displays quarterly production units (in thousands) for three factories (A, B, C) across four quarters. Factory A: Q1=120, Q2=130, Q3=125, Q4=140. Factory B: Q1=100, Q2=110, Q3=115, Q4=130. Factory C: Q1=150, Q2=145, Q3=155, Q4=160. Which factory had the greatest percentage increase in production from Q1 to Q4?
✓ Correct Answer: Option B
Factory A: (140-120)/120 = 16.67%. Factory B: (130-100)/100 = 30%. Factory C: (160-150)/150 = 6.67%. Factory B had the greatest percentage increase.
