Calculation:
Let's assume the marked price of the goods is 'M'.
The retailer offers a discount of 20%, which means the selling price is 80% of the marked price.
Since the retailer sells at cost price, the selling price is equal to the cost price.
Therefore, the selling price is 80% of the marked price, which can be written as:
80/100 * M = M

Simplifying:
80M/100 = M
80M = 100M
100M - 80M = 0
20M = 0
M = 0

Explanation:
It seems that there is an error in the given information. The marked price cannot be zero. Without a valid marked price, it is not possible to calculate the percentage markup. Hence, none of the options (a) 20, (b) 25, (c) 30, or (d) 40 can be considered as the correct answer.

However, if we assume that the marked price is non-zero, we can calculate the percentage markup. Let's consider the case with a marked price of 'M' and a selling price of 'S', where the retailer offers a discount of 20%.

The selling price is given by:
S = M - (20/100) * M
S = M - 0.2M
S = 0.8M

Since the selling price is equal to the cost price:
S = CP
0.8M = CP

The percentage markup can be calculated as:
Markup % = (S - CP) / CP * 100
Markup % = (0.8M - 0.8M) / 0.8M * 100
Markup % = 0 / 0.8M * 100
Markup % = 0

In this case, the percentage markup is zero. However, it is important to note that this calculation assumes a non-zero marked price and does not match any of the given options.

Therefore, the correct answer cannot be determined based on the given information.
