An article is sold at 12.5% profit. If it had been sold at 5% loss, the selling price would have been Rs.9.80 less. The cost price of the article is:
1. Rs.58
2. Rs.56
3. Rs.54
4. Rs.46

• Let x be the Cost price
  Then SP = x*112.5/100
  SP = 1.125x
  
  If it is 5% loss, then
  SP = x*95/100
  SP = 0.95x
  
  1.125x - 0.95x = 9.80
  0.175x = 9.80
  x = 56
  
  Ans : Rs.56

• (112.5-95)x/100=9.8
  x=56

• 2.56
  x*(112.5/100)=y..(i)
  x*(95/100)=y-9.80..(ii)..
  from (i)&(ii) we will obtain 56

• SP= x*(112.5/100)
  SP=1.125x
  
  now after 5% Loss
  Sp=x*(95/100)
  Sp=0.95x
  now,
  1.125x-0.95x=9.80
  0.175x=9.80
  x=56
  hence 56 is ans.

• let cost is x;
  (x+(x*12.5/100))-(x-(x*5/100))=9.80

• option2.) 56 let cp=x
  s.p.=x*(112.5)/100
  s.p.-9.80=x*95/100
  (112.5x/100 )-9.80=95x/100
  solving this we get x=56

• (112.5-95)=17.5
  9.80*100/17.5=56
