Explanation

To find number of articles sold, we need selling price and either profit or cost price. Statement II gives cost price (Rs 632). Statement III gives selling price per article (Rs 765). Profit per article = Rs 765 - Rs 632 = Rs 133. Total profit (Statement I) is Rs 1596. Number of articles = Total profit ÷ Profit per article = 1596 ÷ 133 = 12. Thus only II and III are needed. Statement I provides the answer, not the data to find it.
