Q1.A team records rejects by cause for one month.

$\begin{array}{l|c} \hline \textbf{Cause} & \textbf{Rejects} \\ \hline \text{Porosity} & 96 \\ \text{Undersize} & 60 \\ \text{Surface mark} & 24 \\ \text{Wrong material} & 12 \\ \text{Other} & 8 \\ \hline \end{array}$

What is the cumulative percentage after the first three causes?
- A.96 percent
- B.90 percent✓ Correct answer
- C.78 percent
- D.48 percent
Explanation
The cumulative percentage is the running total of the ranked causes divided by the grand total.

The total is $96 + 60 + 24 + 12 + 8 = 200$ rejects. Taking the three largest causes:

$\frac{96 + 60 + 24}{200} = \frac{180}{200} = 0.90 = 90\%$

The distractor of $78$ percent is the cumulative figure after two causes, which is the value people report when they stop one bar early.
