Gold depreciated at a rate of per year between 2000 and 2005. If 1 kg of gold cost dollars in 2001 and dollars in 2003, how much did it cost in 2002 ?

(C) 2008 GMAT Club -

m25#6Here thee rate of depreciation is given as x% , however while solving they have considered depreciation to be a constant. is this correct

for example if depreciation is 5%, in 2000 if price is 100, then 2001 is 95 , 2002 is 90.25.

but if you consider this depreciation of 5% as a constant 5, then the prices are totally different.

could anyone help
