Although Snoggs's reason for wishing to take his rise at 2, 10s. half-yearly did not concern our puzzle, the fact that he was duping his employer into paying him more than was intended did concern it. Many readers will be surprised to find that, although Moggs only received 350 in five years, the artful Snoggs actually obtained 362, 10s. in the same time. The rest is simplicity itself. It is evident that if Moggs saved 87, 10s. and Snoggs 181, 5s., the latter would be saving twice as great a proportion of his salary as the former (namely, one-half as against one-quarter), and the two sums added together make 268, 15s.
