Answer:
The answer to your question is: Japan
Step-by-step explanation:
Mobile cost in Spain = € 352.5
Mobile cost in Japan = ¥39856
Exchange rate = £1 = €1.41 
                            £1 = ¥188
Cost of mobile in pounds 
                        £ 1 ------------------ € 1.41
                         x  -----------------   €352.5
                        x = (352.5 x 1) / 1.41
                        x= £250
                       £1   ------------------  ¥188
                       x    ----------------- -¥ 39856
                      x = (39856 x 1) / 188
                      x = £212
Then, it was cheaper in Japan
