Q. 14 men can do a work in 5 days working 4 hours a day. In how many days can 7 men do the same work, working in 10 hours a day?
Option
a) 4
b) 8
c) 12
d) 16
Read Solution (Total 3)
-
- Total number of man hours required for the job is 14 * 5 * 4= 280 manhours
As the work is the same, even in the second case, same number of manhours are needed.
So, number of days = 280/(7 *10) = 4 days.
Answer is 4 days.
