Question

An assembly line inspector inspected 340 machine parts. 323 of the parts passed inspection. What percent of the machine parts did NOT pass inspection?

Answer 1

5% did not pass inspection

Explanation:

Given

`Inspected= 340`

`Passed = 323`

Required

Determine the percentage of parts that didn't pass inspection.

First, we need to calculate the number of those that didn't pass inspection.

`Failed = Inspected - Passed`

`Failed = 340 - 323`

`Failed = 17`

Next, we calculate the percentage as follows:

`\% = (Failed)/(Inspected) * 100\%`

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%

So:

`\% = (17)/(340) * 100\%`

`\% = (17 * 100\%)/(340)`

`\% = (1700\%)/(340)`

`\% = 5\%`

5% did not pass inspection
