Can He Pay His Income Tax in Barley Corns?
A thrasher worked 20 days for a farmer, and received for the first days work four barley-corns, for the second 12 barley-corns, for the third 36 barley-corns, and so on, in triple proportions geometrically. I demand what the 20 day’s labour came to supposing a pint of barley to contain 7680 corns, and the whole quantity to be sold at 2 s. 6 d. per bushel?
