Answer 3

To find the percentage of pens that are not suitable for sale, we need to calculate the ratio of pens that are not suitable for sale to the total number of pens.

Given that out of 200 pens, 185 are suitable for sale, we can calculate the number of pens that are not suitable for sale by subtracting the number of suitable pens from the total number of pens:

Total number of pens - Number of suitable pens = Number of pens not suitable for sale 200 - 185 = 15

Therefore, there are 15 pens that are not suitable for sale.

To find the percentage, we divide the number of pens not suitable for sale by the total number of pens and multiply by 100:

(15 / 200) * 100 = 7.5%

So, 7.5% of all the pens are not suitable for sale.
