Answer:
Step-by-step explanation:
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
