Answer» According to the problem given , Selling price of the exhaust fan = S.P = Rs 7350 Let the cost price of the exhaust fan ( C.P ) = Rs x Gain = 1 / 6 of C.P = x / 6 We know that , Cost price = Selling Price - Gain x = 7350 - x / 6 x + x / 6 = 7350 ( 6x + x ) / 6 = 7350 7x / 6 = 7350 x = 7350 × ( 6 / 7 ) x = 1050 × 6 x = 6300 Therefore , Cost price of the exhaust fan = x = Rs6300 Let C.P of watch For Mohit = xMohit Sold It At a profit of 10%So,S.P of Mohit = x + 10x/100 = 110x/100 = 11x/10S.P of Mohit = C.P for KarimNo, Karim sells it at a profit of 4%So S.P of Karim = 11x + 11x * 4 ------ ------------ 10 10 * 100 = 1100x + 44x / 1000 S.P Of karim = C.P of RahimBut Rahim Pays 14300 for it Therefore, 1144x /1000 = 14300x = 14300 * 1000/1144x = Rs12500 Therefore, Mohit Buys The Watch For Rs 12500 |
