Yes good point. And in any case, for "five rupees, or about 13 cents" to be correct, we'd need a cent to be about 5/13 ≈ 0.38 rupees, and that fits neither USD (1 USD ≈ 65 INR) nor GBP (1 GBP ≈ 86 INR). So original point in this thread, that the article's conversion is mystifying/wrong, still holds.
