Question

Ahmad has some files.

He gave 3/5 of the files and had 14 files left.

How many files did he have at first?​

Answer 1

35 files

Explanation:

gave=3/5

left=2/5 = 14f

had= 5/5

2/5=14

5/5

5×14÷2 = 35

Answer 2

The answer is 35

Explanation:

Let the number of files he had be x

He gave 3/5 of the files

That's

3/5x

After that he still had 14 files left which means when we subtract 14 from the original files we should get 3/5 of the original files

So we subtract 14 from the original number of files

That's

x - 14

We equate the two statements

that's

`(3)/(5) x = x - 14`

Multiply through by 5

`5 * (3)/(5) x = 5x - 70`

We have

3x = 5x - 70

3x - 5x = 70

-2x = - 70

Divide both sides by -2

We have the final answer as

x = 35

Therefore he had 35 files at first

Hope this helps you
