Question

If 100 KB file is stored in 2 MB folder how many files can be stored in the folder​

Answer 1

20 files.

Step-by-step explanation:

Given the following data;

Size of file = 100 kilobytes.

Folder size (memory) = 2 megabytes.

Method 1

1000 kilobytes = 1 megabytes.

100 kilobytes = x megabytes

Cross-multiplying, we have;

1000x = 100

x = 100/1000

x = 0.1 mb

Now, to find the number of files that can be stored;

`Number \; of \; files = \frac {Memory}{Size \; of \; each \; file}`

Substituting into the equation, we have;

`Number \; of \; files = \frac {2}{0.1}`

Number of files = 20 files.

Method II

We know that;

• 1 kilobytes = 0.001 megabytes.
• 100 kilobytes = 0.1 megabytes.
• 1000 kilobytes = 1 megabytes.
• 2000 kilobytes = 2 megabytes.

Substituting into the formula, we have;

`Number \; of \; files = \frac {Memory}{Size \; of \; each \; file}`

Substituting into the equation, we have;

`Number \; of \; files = \frac {2000}{100}`

Number of files = 20 files.
