The ratio of cost price and selling price of an article is c : d. If d is 150% of c then the percentage of profit on cost price is:
If d is 150% of c.
d = 150% of c
d = 1.5c  Eq.(i)
cost price = c
selling price = d = 1.5c [From Eq.(i)]
Profit percentage =Â $$\frac{\left(1.5c-c\right)\times\ 100}{c}$$
=Â $$\frac{0.5c\times\ 100}{c}$$
= 50%
