A shopkeeper bought an article at Rs1OOO and marked up its price by x%...
Let's assume the cost price of the article is C.

The shopkeeper marked up the price by x%. Therefore, the selling price of the article is C + (x/100)C = (100 + x)C/100.

Given that the shopkeeper gave a discount of (2x/5)% on the selling price, the discounted price is [(100 + x)C/100] - [(2x/5)(100 + x)C/100] = [(5000 + 100x - 2x^2)/(5000)] * (100 + x)C/100.

The shopkeeper still made a profit of (2x/5)%. Therefore, the profit earned is [((5000 + 100x - 2x^2)/(5000)) * (100 + x)C/100] - C = (2x/5)% of C.

We can equate the profit earned to (2x/5)% of C:

[((5000 + 100x - 2x^2)/(5000)) * (100 + x)C/100] - C = (2x/5)C.

Simplifying the equation, we get:

[((5000 + 100x - 2x^2)/(5000)) * (100 + x)/100] - 1 = 2x/5.

Solving this equation will give us the value of x, which represents the discount given by the shopkeeper.

By solving the equation, we find that x = 50.

Therefore, the amount of discount given by the shopkeeper is 50.

The correct answer is (d) 50.
