Calculations help

I am doing a tax return for a friend and would like some help with calculation please.

My friend has earned 1,892.25 in interest for year 2009/10 the revenue rate for there are two spot rates for euro for 2009 are below:

Spot rate on 31.03.10 - (Euro 0.89198 = Sterling 1.1211) and 31.03.10 (euro 0.88511 = sterling 1.1298)this is up to 5 April 2010.

Spot rate on 31.12.09 -(Euro 0.88849 = Sterling 1.1255) and 31.12.09 (euro 0.89008 = sterling 1.1235)
Spot rate on 31.03.09 -(Euro 0.92627 = Sterling 1.0796) and 31.03.09 (euro 0.83043 = sterling 1.2042)

Got this link on this board for which I am grateful as I am hopless with maths and do not know how to work it out. Please help.

edit: seems it a uk return you are doing. ignore my initial post

I would still like your help with this. Savings are in an Irish Bank. Thanks

I'm guessing here as I don't know the HMRC rules for converting Irish deposit interest to a Sterling equivalent [e.g. should it be the gross Irish interest or the net Irish interest?] but on the basis of the link you supplied, it seems that you could multiply the Irish deposit interest by the average value for the year to 31-3-2010 to get a Sterling equivalent==> €1892.25 x 0.88511 = £1674.85.
