Let marked price = 100
90 = (120/100)*cp, cp = 75
Now discount = 20% so, SP = 80
% profit = [(80 – 75)/75]*100 = 20/3

If a discount of 10 percent is given on the marked price of the articl...
Let's assume the marked price of the article is M.
Given that a discount of 10% is given on the marked price, the selling price (S) can be calculated as:
S = M - (10/100)M
S = M - 0.1M
S = 0.9M
We are also given that the seller gains a 20% profit on the marked price. Profit is calculated as the difference between the selling price and the cost price (C), so we can write:
Profit = S - C
Since the seller gains a 20% profit, we can say:
Profit = (20/100)M
We want to find the percentage profit if the article is sold at a 20% discount. Let's calculate the selling price after a 20% discount:
S' = S - (20/100)S
S' = 0.8S
Now, let's substitute the value of S in terms of M into the equation above:
S' = 0.8(0.9M)
S' = 0.72M
We can calculate the cost price (C) by subtracting the profit from the selling price:
C = S' - Profit
C = 0.72M - (20/100)M
C = 0.72M - 0.2M
C = 0.52M
Now, let's calculate the profit percentage when the article is sold at a 20% discount:
Profit% = (Profit/C) * 100
Profit% = [(20/100)M / (0.52M)] * 100
Profit% = (20/52) * 100
Profit% = (500/13) ≈ 38.46
Therefore, the percentage profit when the article is sold at a 20% discount is approximately 38.46%, which is option B.
