Total CP=3240Rs.
Let CP of 1=x
Profit=15%
Sp= 115*x/100
CP of other=3240-x..[since total=3240]
loss=9%
SP= (3240-x)*91/100
Given overall no gain no loss
Means, Total CP = Total SP
3240 = 115x/100 + (3240-x)*91/100
3240*100 = 115x +3240*91 - 91x
3240*(100-91) = 24x
3240*9 = 24x
x=1215Rs.
3240-x= 2025Rs.
CP of fan @ 15%profit=1215
CP of fan @ 9%loss=2025
