Question

If 90% is 30% of a number, what is 200% of that number?

Answer 1

To solve this problem, we have to use the following proportion

`(90)/(z)=(30x)/(200x)`

Where z represents 200% of the number

`\begin{gathered} (90)/(z)=(3)/(20) \\ z=(90\cdot20)/(3) \\ z=600 \end{gathered}`

Hence, 200% of that number is 600%.
