It is given that
C.P of an article =₹1,200
We know that
S.P =5/4 of C.P
Substituting the values
S.P=5/4×1200=₹1,500
Gain = S.P – C.P
=1500–1200
=₹300
Gain percent =(gain×100)/C.P
=(300×100)/1200
=25%
The cost price of an article is 90% of its selling price. What is the profit or the loss as percent ?
