Question 761038
Selling price = Rs. 300
Profit = 20% of Selling price or 0.2 of selling price (Because 20% = 20/100 = 0.2)

So, profit = {{{300*0.2=60}}}

Profit = Rs 240

Cost price = Selling price - Profit

Therefore, cost price = {{{300 - 60 = 240}}}

Cost price = Rs 240

So, profit as a percentage of cost price = {{{60/240 = 0.25 = 25 per cent}}}

Answer: 25%
