In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?

A. 30% B. 70%
C. 100% D. 250%

• Let the cost price is Rs.100, The Selliing price is Rs(100+320)=Rs.420
  Now if the cost price increases by 25%, the cost would become Rs(100+25)=Rs.125
  NEW PROFIT =420-125=Rs.Rs.295
  %age of the profit on selling price=(295/420)*100=70%(approx)

• Let C.P =100 therefore S.P =420
  new C.P =125
  P = (420-125) = 295
  P% = (295/125)*100
  = 256
  
  ans= 250 approx.

• 70%
  
  If in first case, C.p. is x, then profit is 3.2 x and SP= 4.2 x
  In 2nd case, Cp becomes 1.25 x, but SP remains same , i.e. 4.2x, then profit = 4.2x-1.25x = 2.95x
  profit as per percentage of selling price = 100*2.95x/4.2 x = approx 70 %

• Let C.P.= Rs. 100.
  Then, Profit = Rs. 320,
  S.P. = Rs. 420.
  
  New C.P. = 125% of Rs. 100 = Rs. 125
  New S.P. = Rs. 420.
  
  Profit = Rs. (420 - 125) = Rs. 295
  
  Required percentage = (295/420) * 100
  = 70%(approx)
