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

(C) 2008 GMAT Club - m25#6

* \(T\frac{S}{2}\)

* \(T\sqrt{\frac{T}{S}}\)

* \(T\sqrt{S}\)

* \(T\frac{S}{\sqrt{T}}\)

* \(\sqrt{ST}\)

Can someone explain why 2002 is K^2S? Why is it squared?
