Conversion Rate for Previous Earning Calculation

Hi,

I have a query regarding Previous Earning conversion rate.

Say I am going to claim my previous earning from 01 Dec 2009 to 30 Nov 2010 and I am going to apply my Tier 1 General on 24th Dec 2010.

On 30th Nov 2010 conversion rate was 1 GBP = 72 INR.
On 24th Dec 2010 conversion rate is 1 GBP = 71 INR. (Let take it 71 Rs).

Now While calculate my previous earnings which value(71 or 72) should I consider?

As per the guidance you need to use the rate on the last day of your earnings (e.g. 30 November).

Also, you need to use the OANDA rate converting from INR to GBP (e.g. it will be below 0.09 - can't remeber the exact rate, but it should be a multiplier, not a rate that you have to divide).
