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

Answer:

16.67% of cases of tapes were sold.

Step-by-step 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:

$20\%\rimes x = 24\\\\\dfrac{20}{100}\times x = 24\\\\x = 24\times 5 = 120$

Thus, total number of tapes =

$=24 + 120 = 144$

Percentage of tapes sold  =

$=\dfrac{24}{144}\times 100\% = 16.67\%$

Thus, 16.67% of cases of tapes were sold.
