what is the increased price?
Please Solve this problem ​

Answer 1

Answer:

Let CP = Rs 100

MP = x%

Discount 10% of MP = 0.10x

SP = Rs 126

Profit = Rs 26

Facts :

MP is always markedup on CP

MP - Disc = SP

(Discount always calculated on MP)

SP - CP = Profit

Now, 126 = x - 0.10x

=> x = 1260/9 = Rs 140

=> Markup = 40% of CP

Actual MP of article = Rs 280

=> Actual CP =280/140 x 100 = Rs 200

Another Solution :

MP = 280

Discount @ 10% = 28

SP = 280 - 28 = 252

Now 252 includes 26% profit.

=> CP = 252/126 x 100 = 200
