Question 1: A store sells a jacket for $120 after applying a 25% discount. What was the original price?
- $145
- $150
- $160 (Correct answer)
- $180
Correct answer: $160
If $120 is 75% of the original price, then original = 120 / 0.75 = $160.

- 58 mph
- 60 mph (Correct answer)
- 62 mph
- 65 mph
Correct answer: 60 mph
Total distance = 420 miles, total time = 7 hours; 420 divided by 7 = 60 mph.

Total work = 8 x 15 = 120 worker-days; 120 divided by 12 = 10 days.
Question 4: What is 15% of 240 added to 20% of 150?
- 60
- 66 (Correct answer)
