RPI formula

Good afternoon,

I have my Financial Performance exam tomorrow afternoon which I am dreading.
I am confused as to which is the correct formula for adjusting sales using the RPI.
In my BPP textbook the formulae is Sales for current year x RPI for year 1/RPI for the current year.
However on my BPP passcards the formula is Actual sales in year Y x Current RPI/RPI for year 1.

Please could someone advise what the correct formula is?

    Assuming the question is asking for Sales at Year 1 prices then:

    Sales for current year x RPI for year 1/RPI for the current year
