    P can complete the work in (12 x 8) hrs. = 96 hrs. Q can complete the work in (8 x 10) hrs. = 80 hrs. P's1 hour's work = 1 and Q's 1 hour's work = 1 . 96 80 (P + Q)'s 1 hour's work = 1 + 1 = 11 . 96 80 480 So, both P and Q will finish the work in 480 hrs. 11 Number of days of 8 hours each = 480 x 1 = 60 days = 5 5 days. 11 8 11 11
