50. Binding Books Challenge In one day a man can bind 200 books and his helper binds one-quarter as many. If they take turns working complete days, how many days will it take them to bind 1000 books? Added 9 November 2013 Show Solution Solution: The man binds 200 books on his days, the helper 50 books (one-quarter of 200). They alternate days, so in each two-day cycle they bind 200 + 50 = 250 books. To reach 1000 books they need 1000 ÷ 250 = 4 cycles, which is 4 × 2 = 8 days.
