Easy### Solution

Option D is the correct answer.

### Option Analysis

x: total cans of peaches

0.015x: number of cans that failed inspection

0.015x*5/6: number of cans that wrong label

0.015x*1/6: number of cans that dented red

Since all the cans that were incorrectly labelled or dented red, there’s no can that both incorrectly and dented red.

Statement I is sufficient: 450 of the cans of peaches inspected yesterday at the plant failed to pass inspection: number of cans that were dented red = 0.015x/6 = 450/6 = 75 => sufficient

Statement II is sufficient: 29,550 of the cans of peaches inspected yesterday at the plant passed inspection.

Total cans that passed inspection = 1 – 0.015x = 29,550 => x=30,000

Number of cans that were dented red = (0.015*30,000)/6 = 75 => sufficient
