Question

30 men working 16 hours per day make a house in 10 days in how many days will 24 men working 18 hours per day to make it

Answer 1

Number of man hours required to complete the work is 30x16x10 = 4800 man hours.

Let the number of days taken be X. Then

24x18X = 4800

Or, X = 4800/(24x18)

Or, X = 100/9

Or, X=11.11

Hence,work will be completed on the 12th day.

hope it will help....☺️
