Interest rate parity formula

Hi
I have the MCQ
A company from Northland is expecting to receive Southland Krone in one year’s time. The spot
rate is Northland dollar 3.4670 per 1 Krone. The company could borrow in Krone at 8% or in
Northland dollars at 13%. There is no forward rate for one year’s time.
What would interest rate parity predict the exchange rate to be in one year?

The formula is

Fo = So * (1+Ic)/(1+Ib)
Ic – interest rate in country c (the overseas country) up to the future date
Ib – interest rate in country b (the base country) up to the future date

I calculate Fo=3.4670* (1+0.08)/(1+0.13)=3.3136

But answer is 3.6275 becouse calculation is Fo=3.4670* (1+0.13)/(1+0.08)=3.6275

I thought base country is Northland, but it’s say that base country is Southland? How to understand it?
