Answer 1

Answer:

13(1/3) %

Step-by-step explanation:

Let C.P.=Rs. 100. First S.P.=Rs. 120

Now, S.P. =Rs. 120, commission=10%

Therefore, Marked Price=[(100/90)X120]=Rs. 400/3.

No, marked price=400/3, commission=15%

Therefore, S.P.=85% of 400/3=[(85/100)X(400/3)]=340/3.

Therefore, Gain%=[(340/3)-100]=40/3=13(1/3)%.
