Answer 1

Answer:

CP of first fan 1592.5  CP of 2nd fan 2012.5

Step-by-step explanation:

Let,

CP1 and SP1 for 1st  fan

CP2 and SP2 for 2nd fan

Given,

each fan was sold for the same price

SP1=SP2

Let CP1=x

     CP2=(3605-x)

We know that SP=((100+gain)/100)*CP

SP1=(100+gain)/100*x

SP2=(100-loss)/100*(3605-x)

(115/100)*x=(91/100)*(3605-x)

115x=3605*91-91x

206x=3605*91

x=1592.5  (CP1)

3605-1592.5=>2012.5 (CP2)
