Suppose you are a euro-based investor who just sold Microsoft shares
that you had bought six months ago. You had invested 10,000 euros to
buy Microsoft shares for US$120 per share; the exchange rate was
US$1.15 per euro. You sold the stock for US$135 per share and
converted the dollar proceeds into euro at the exchange rate of
US$1.06 per euro.

First, determine the profit from this investment in euro terms. 
Second, compute the rate of return on your investment in euro terms.
How much of the return is due to the exchange rate movement?

Please show all calculations

Profit = ?10,000 X $1.15/? / $120/share X $135/share / $1.06/? - ?10,000 = ?2205.19

Rate of Return = ?2205.19/?10,000 = 22.05%

Rate of Return from exchange-rate movement = (?10,000X $1.15/? /
$1.06/? - ?10,000) / ?10,000 = 8.49%

Sincerely,

I had calculated rate of return in a arse about way, and came at
21.55%. Double checking I found the error and got a similar result.
Thanks!

My only comment is that brackets would have added extra clarity
