Question 1

A warehouse receives 1,440 packages in 8 hours. If the rate remains constant, how many packages are received in 3 hours?

Accepted Answer

540

Answer

1,440 ÷ 8 = 180 packages per hour. 180 × 3 = 540 packages.

Question 2

If a fulfillment center processes orders at 95% accuracy and handles 2,000 orders daily, how many errors occur per day?

Accepted Answer

100

Answer

Error rate = 100% - 95% = 5%. 5% of 2,000 = 0.05 × 2,000 = 100 errors.

Question 3

A delivery route covers 6 stops in 90 minutes. At the same rate, how many stops can be covered in 4 hours?

Accepted Answer

16

Answer

Rate = 6 stops / 90 min = 1 stop per 15 min. 4 hours = 240 min. 240 ÷ 15 = 16 stops.

Question 4

Which number comes next in the series: 3, 6, 12, 24, ?

Accepted Answer

48

Answer

Each number doubles: 3×2=6, 6×2=12, 12×2=24, 24×2=48.

Question 5

If 5 workers sort 750 items in 3 hours, how many items can 8 workers sort in 2 hours at the same rate?

Accepted Answer

800

Answer

Rate per worker per hour = 750 ÷ (5 × 3) = 50 items. 8 workers × 2 hours × 50 = 800 items.
