The Cost Price (CP) of the article is ₹80.
The article was marked 25% above the CP.
MP=CP+25% of CP
MP=80+10025×80
MP=80+41×80
MP=80+20
MP=₹100
The article was sold for a Selling Price (SP) of ₹81 after a discount of X% on the MP.
Discount=MP−SP
Discount=100−81
Discount=₹19
The discount percentage X% is calculated on the MP:
X%=MPDiscount×100
X=10019×100
X=19
So, the discount percentage is 19%.
The original marked price (MP1) is ₹100.
The marked price is increased twice successively by X%=19%.
New Marked Price (MP2)=MP1(1+100X)(1+100X)
MP2=100(1+10019)(1+10019)
MP2=100(100119)(100119)
MP2=100119×119
MP2=10014161
MP2=₹141.61
The article is now sold at this new marked price, so the New Selling Price (SP2) is ₹141.61.
The Cost Price (CP) remains ₹80.
When SP was ₹81:
Profit1=SP1−CP
Profit1=81−80
Profit1=₹1
When SP is ₹141.61:
Profit2=SP2−CP
Profit2=141.61−80
Profit2=₹61.61
The percentage by which Profit2 is more than Profit1:
Increase in Profit=Profit2−Profit1
Increase in Profit=61.61−1
Increase in Profit=₹60.61
Required Percentage=Profit1Increase in Profit×100
Required Percentage=160.61×100
Required Percentage=6061%
Therefore, the profit would be 6061% more than the profit when the selling price was ₹81.
