Given,
List price of table fan = Rs 480
M.P. = 480
Retailer buys it at discount 25%
Cost price for the retailer is \((\frac{75}{100})\)x 480
C.P. = \((\frac{75}{100})\)x 480
C.P. = 36
Retails sells it to get 15%
15% = \(\frac{S.P.-C.P.}{C.P.}\)x 100
S.P. = \(\frac{115}{100}\)C.P.
S.P. = \(\frac{115}{100}\)X 360 = 414
S.P. = 414
Retailer should sell it for Rs 414 to get 15% gain
