Answer: C

Explanation:

To find out how much B paid A for the article, we can use the formula for profit:

Selling price = Cost + Profit

In this case, the selling price is 400 and the profit is 20%, so:

S.P FOR B = 400 + (20/100) * 400

This simplifies to:

S.P FOR B= 400 + 80

So B paid 400 +80 = 480 for the article.

To find out how much C pays B, we can use the same formula:

Selling price = Cost + Profit

In this case, the selling price is the amount that C pays, the cost is the 480 that B paid to A, and the profit is 10%. So:

Selling price = 480 + (10/100) * 480

This simplifies to:

Selling price = 480 + 48

So C pays 480 + 48= 528 to B.
