I think it's something like
£780 is 120% because the original price is 100% and you have added 20% .
So then you do 780 divided by 120, and then multiply it by 100 and you get the original price which is £650.
I hope that makes sense, I'm not very good at explaining, but this is how i was taught to do similar problems

Since the sale price includes the 20% VAT, then it is 120% of the price before taxes
In other words,
780 = 1.2x

When you want to find an original price after some other cost has been added, you should divide by the ratio of the new price to the old price.
You know that the new price is 120% of the old price, right? And 120% is the same as 1.20.
So do this:
original/new price ratio
780/1.20
Which equals 650.

original price of tv + 20%(original price of tv) = 780. Plug in a variable for "original price of tv" and solve the equation

( ( [VAT Rate] + 100 ) / 100 ) * [Original Price] = [Total Price Including VAT]
((20+ 100)/(100)) * (Original Price) = 780
Original Price = 650
