A trader incurred 15% loss by selling a radio for rs 510 . what should have been the selling price to make 25/4 % profit on selling price ?

• 637.5 Rs.
  
  If cost price of a radio=x, then given x*(85/100)=510, so x=600
  To make 25/4=6.25 profit, the selling price=600*1.0625= 637.5

• Rs 640
  
  Let sp be x
  Then profit = (25/400)*x = (1/16)*x
  cp=x-(1/16)*x=(15/16)*x
  Profit percent on cp=[(1/16)*x*100]/[(15/16)*x]=20/3 %
  
  cp of radio when sp is rs 510 & loss is 15%=510/0.85=rs 600
  
  sp of radio to fetch a profit of 25/4% on sp or 20/3% on cp=600+600*(20/300)=rs 640

• =15% loss on 510.
  mins we have to find cost price.
  cost= 100%-15%=85
  =510*100/85
  =600
  =cost price=600 and now 25/4%
  =25/4=6.25%
  =600*100/6.25
  =37.50
  =600+37.50
  =637.50
