No. of articles = 80
Cost Price of articles = Rs 2,400 and Profit = 16%
∵ Cost price of articles is Rs 100, then selling price = 100 + 16 = Rs.116
∴ Cost price of articles is Rs 1, then selling price = 116100
∴ Cost price of articles is Rs 2400, then selling Price = 116100×2400=Rs.2784
Hence, Selling Price of 80 articles = Rs. 2784
Therefore selling price of 1 article =278480=Rs.34.80
