Question

A company that makes hair care products at 9000 people try a new shampoo. Of the 9000 people, 18 had a mid allergic reaction. What percent of the people had a mid allergic reaction

Answer 1

0.2% of the people had mid allergic reaction.

Explanation:

Given that:

Number of people tested for a new shampoo = 9000

Number of people who had allergic reaction = 18

Percent of people =
`(People\ who\ have\ reaction)/(Total\ number)*100`

Percent of people =
`(18)/(9000)*100`

Percent of people = 0.002 * 100

Percent of people = 0.2%

Hence,

0.2% of the people had mid allergic reaction.
