The cost of a certain fabric is directly proportional to its length for a given width. If the cost of 8 meters of the fabric is ₹3,200, what will be the cost of 25 meters of the same fabric?
₹10,000
As cost is directly proportional to length, the cost per metre is constant.
Cost of 1 metre \(= \frac{3200}{8} = 400\) rupees.
Cost of 25 metres \(= 400 \times 25 = 10000\) rupees.
Hence, the cost of 25 metres of the fabric is ₹10,000.
