Correct answer: Q3
In Q3, Product Y (610) exceeded Product X (580) for the first time.
Question 2: A data set shows percentage change in costs year over year: Year 1 = +5%, Year 2 = -3%, Year 3 = +8%, Year 4 = -2%. What is the overall net percentage change across all 4 years?
- +8% (Correct answer)
- +6%

Net change = 5 − 3 + 8 − 2 = +8% cumulative change over four years.
Question 3: A table shows pass rates for three test centers: Center 1 = 78%, Center 2 = 85%, Center 3 = 71%. If 200 candidates tested at Center 2, how many passed?
- 150
- 160
- 170 (Correct answer)
- 180
Correct answer: 170
85% of 200 = 0.85 × 200 = 170 candidates passed at Center 2.
Question 4: A graph shows inventory levels at the start of each week: Week 1=500, Week 2=430, Week 3=360, Week 4=290. If the pattern continues, what will the inventory be at the start of Week 5?
- 220 (Correct answer)

Correct answer: 220
The inventory decreases by 70 each week; 290 − 70 = 220 for Week 5.
Question 5: A table shows two salespeople's monthly totals. Alex: Jan=$4,200, Feb=$3,800, Mar=$4,600. Sam: Jan=$3,900, Feb=$4,100, Mar=$4,400. Who had the higher total over all three months?
- Alex (Correct answer)

Alex total = $12,600; Sam total = $12,400 — Alex had the higher combined total.
Question 6: A chart shows absenteeism rates: Dept A = 4.2%, Dept B = 2.8%, Dept C = 6.1%, Dept D = 3.5%. Department C wants to reduce its rate to match the company average. What is the company's average absenteeism rate?
- 3.9%
- 4.0%
- 4.15% (Correct answer)

Average = (4.2 + 2.8 + 6.1 + 3.5) ÷ 4 = 16.6 ÷ 4 = 4.15%.
