Answer» Let quantity of one type of rice= 3xLet quantity of other type of rice be 2x Then,Total Cost price of rice CP= 3x35 + 2x45= 105x + 90x= 195x Selling price of rice= 5x41.60= 208x Therefore,Gain % = [(SP - CP) / CP]100=[(208x - 195x)/195x]*100= 1300/195= 6.6 %

Answer»

Let quantity of one type of rice= 3xLet quantity of other type of rice be 2x

Then,Total Cost price of rice CP= 3x*35 + 2x*45= 105x + 90x= 195x

Selling price of rice= 5x*41.60= 208x

Therefore,Gain % = [(SP - CP) / CP]*100=[(208x - 195x)/195x]*100= 1300/195= 6.6 %
