If 120% is £360 what is 100%

In this question a vital information has been provided. This information can be used for determining the answer to the question that is asked. It is given that 120% of a certain number is 360 pound. The 100% value of the number needs to be determined.

Let us assume the number to be = x

Then

120x/100 = 360

12x/10 = 360

12x = 360 * 10

12x = 3600

x = 3600/12

= 300

Now we can say that the 100% of the number or the actual number is 300 pounds. I hope the problem is clear to you and you can understand the trick involved in the question.
