A shopkeeper gives a discount of 20% on the sale. By what percent he had to increase the S.P of the item so that after giving discount he got the price of the its C.P.

• Let CP be 100rs
  20% discount
  100 * 80/100 = 80rs
  so SP =80rs
  
  to get CP again , calculate
  x% of SP = 100 (here 100 is CP)
  80 * x/100 = 100
  x = 125%
  125 % of SP is CP
  
  Therefore % increase is 125 - 100 = 25%
  
  Ans : 25%

• just use this formula for this type of question:
  
  (A/(100+or-A))*100
  
  here A is given Percentage

• this problem can be solved by the method of successive percentage....
  
  -20+x+(-20*x/100)=0
  
  here i have written 20 as a negative value because its a discount and x is the required value so it should be positive ...and net value should be 0....
  
  
  solve above equation and get x=25%
  
  
  
  note:successive percentage formula= a+b+(ab/100)
