The sale price of an article including sales tax is 1232. The rate of sales tax is 10%. If the shop keeper has made a profit of 12% then the cost price of the article is?

• ans : RS1000
  
  SP including tax = MP *(1+tax rate/100)
  1232 = MP*(1+10/100)
  MP = 1120 (MP ---> marked price, SP---> selling price)
  
  MP = SP = 1120
  P% = 12
  CP = SP * (100/(100+P%)
  CP = 1120* 100/112
  = 1000

• let cost price of article=x
  sale price=(x+10x/100)=11x/10
  11x/10*12/100+11x/10=1232...................(1)
  on solving equation (1)
  x=1000
