The table shows the daily output (in units) of five machines over four days: Day 1: M1 = 150, M2 = 140, M3 = 180, M4 = 130, M5 = 160; Day 2: M1 = 160, M2 = 135, M3 = 190, M4 = 135, M5 = 165; Day 3: M1 = 155, M2 = 145, M3 = 185, M4 = 140, M5 = 170; Day 4: M1 = 165, M2 = 150, M3 = 195, M4 = 145, M5 = 175. Find the average daily production of Machine M3.
- 187.5
- 185
- 190
- 182.5
Correct answer: 187.5
Solution
The average daily production is the total output over 4 days divided by 4. For M3, the outputs are 180, 190, 185, and 195, whose sum is 750. So the average is 750/4 = 187.5 units.
