Question

Working together, p, q and r reap a field in 6 days. If p can do it alone in 10 days and q in 24 days, in how many days will r alone be able to reap the field?

Answer 1

Answer:

40 days

Step-by-step explanation:

one field reap by p,qandr= 1/6

one field reap by p= 1/10

one field reap by q = 1/24

one field reap by r = 1/x

from the question

1/10 + 1/24 + 1/x = 1/6

5+12 +1/x = 1/6

120

1/x= 20-17/120

x = 120/3

x= 40 days .
