Question

A video merchant sold 24 cases of tapes, which was 20% of what he had left. What percent of tapes did he sell?

Answer 1

16.67% of cases of tapes were sold.

Explanation:

We are given the following in the question:

Number of cases of tapes sold = 24

Thus is 20% of tapes left.

Let x be the total number of tapes left.

Thus, we can write:

`20\%\rimes x = 24\\\\(20)/(100)* x = 24\\\\x = 24* 5 = 120`

Thus, total number of tapes =

`=24 + 120 = 144`

Percentage of tapes sold =

`=(24)/(144)* 100\% = 16.67\%`

Thus, 16.67% of cases of tapes were sold.
