thanks a lot everybody
 my  real doubt is
in sum books
 percentage change in REAL exchange rate=% change change in exchange rate + 
                                                                       % change in prices of the economies

whreas, in krugman    
percentage change in REAL exchange rate=% change change in exchange rate  -
                                                                       % change in prices of the economies

so what is the correct formula..which one should i adopt..
