Had Dhaniram bought an item at 10% less and sold it at 10% more, he would have doubled his profit percentage. If x was the original profit percentage, which of the following ranges does x fall ?
A. 29%-23%
B. 22%-17%
C. 16%-10%
D. Data insufficient

• Let us calculate for an item that is of Rs.100/-
  Given ,Cost price = 90, Selling price = 110/-
  Profit % = (SP-CP)/CP *100 = (110-90)/90*100 = 22.22
  Therefore, original profit percentage = Half of 22.22 = 11.11
  So correct option is C.16%-10%

• Let sp of item for dhaniram=100
  Less percentage=10
  Cp of dhaniram=90
  Dhaniram sells item 10 percent more of sp of item for dhaniram
  Dhaniram sp=100+10=110
  Profit of dhaniram=110-90=20
  Profit percentage=20/90 *100=22.22=double of original profit(x) percentage
  Original profit percentage x=22.22/10=11.11

• correct ans is A.
  first time c.p =x and s.p=y
  sec time c.p=9x/10 and s.p=11y/10
  
  2(y-x)/x=(11y/10-9x/10)/9x/10
  solving this
  y=9x/7
  
  here we get 28.5%
  
  how could you take 10% of 100 for selling price. when your cp =90.

• cp=90 sp=110
  p=20
  p%=(20*100)/90 =22.22
  since its double the profit,divide by 2
  x=22.22/2 =11.11
