17 men 7 hours 2 days
1 man 1 hour = 1/238 work
Now men 6 hour = women 9 hours
So, men 1 hour = women 9/6 hours
1 women 1 hour work = (1/238)*(6/9) = 1/357
Similarly men 6 hour = boys 10 hour
So, 1 boy 1 hour work = 3/1190
Now, 15 men, 15 women and 15 boys ,
(15/238)+(5/119)+(9/238) = 34/238 = 1/7 = 7 hours.
Now, working 7 hours per day = 7/7 = 1 day(Ans)
