Vat control- practice sypnotic ass question

LA2018

Hey,
So this question in regards to the VAT control and the errors. I think I’m confusing myself as I may be reading the question wrong.
Sales - the invoice put on as sales rafer then Vat. Do I need to deduct the value of the error or do I need to work out how much the invoice would be including that amount of vat?
?

The Vat wasn't included in the control account so it needs to be added to the correct side (credit) this will increase the brought down balance on the debit side.
