Question

The CP of an article is RS.2400 and it is marked at 25% above the CP. Find profit and profit percent, if sold at 15% discount

Answer 1

  Since Mark price is 25% above Cost prices so MP of the article will be =1.25*2400  =Rs 3000  Now since the article is sold at 15% discount so the Selling price will be 3000*.85=Rs 2550     Now profit =, Sp-Cp  2550-2400  =150  Profit%=(150/2400)*100  6.25%  

Answer 2

★Given, cost price ( C.P) 100% = 2400
★since ,it is marked at 25% above the cost price, then

market price( M.P)

= 125 % of 2400= 125 / 100 × 2400

= Rs.3000

sold at discount = 15% (-ve)

now selling price (S.P) =(100 - 15) % of Rs.3000

= 85% of Rs.3000

= 85 / 100× 3000 = 85 × 30= Rs. 2550

Net Profit = S.P - C.P = 2550 - 2400

= Rs.150

★now come to the short cut method for
percentage change , ★★

%change = a + b + ab / 100

let, a = 25 ( +ve) , discount (b) = - 15

%change = 25 + ( -15 ) + ( 25 ) ( - 15 )/100

= 25 - 15 - 375 / 100

= 10 - 3.75 = 6.25 % ( +ve means profit )

hence ,his profit percentage = 6.25 %
