Answer» here is a similar question- Suppose the cost price of chair isx.When it is sold at a gain of 8%.Then, selling price of chair =x+8x100=108x100When it is sold at a gain of 15%.Then, selling price of chair =x+15x100=115x100Now, according to the question, a dealer gets Rs.56 less if instead of selling a chair at a gain of 15%, it is sold at a gain of 8%So we have;115x100−108x100=56⇒7x100=56⇒x=56×1007=800Therefore the cost price of chair is Rs.800. |
