Question

apple is having 20% off so I bought my iPad for £40 how much was it originally 

Answer 1

£50

==================

Let the original price be x.

We know that after 20% discount the price is £40.

Set us the following equation and solve for x:

• x - 20% of x = £40
• x - x*(20/100) = £40
• x - 0.2x = £40
• 0.8x = £40
• x = £40/0.8
• x = £50

So the initial price was £50.
