Kumar, a book store owner sells 10 pens at a profit of 12% .If he had sold it at a loss of 12% then he would have
got Rs.60/- less. At what price did Kumar buy the pens for?

• If CP is x, then profit in first case = 0.12x and loss in 2nd case = 0.12x
  
  Diff in amount recd in two cases = 0.24x
  As per given condition
  0.24x = 60
  x= 60*100/24 = Rs 250.
  
  so he bought 10 pens for Rs 250 @ Rs 25 per pen.

• CP of each pen Rs.37.5 and for ten pens Rs.375
  Let the cost of each pen be Rs.x
  Then SP at 12% profit 112x/100
  And for 10 pens the SP is 112x/10
  Now SP of each pen at 12% loss: 88x/100
  SP for ten pens :88x/100
  Now the equation is : (112x/100)-(88x/100)
  Solving x= Rs.37.50
