If there is a profit of 20% on the cost price, then the percentage of profit on the sale price is:

Correct option is A

Given:

Profit on Cost Price (CP) = 20%

Formula Used:

Profit % on SP = $$\frac{\text{Profit}}{\text{SP}} \times 100$$​​

Solution:

Let Cost Price = Rs 100
Then Profit = 20% of 100 = Rs 20

So, Selling Price = 100 + 20 = Rs 120

Profit % on SP = $$\frac{20}{120} \times 100 = \frac{1}{6} \times 100 = 16\frac{2}{3} \%$$​​
