Step-by-step explanation:
1st man work in 1 hour work =1/6
2nd man work in 1 hour work =1/4
1st man 2 hour work =2*1/6=1/3
work left after 2 hour =1-1/3=2/3
Two men 1 hour work =1/6+1/4=5/12
5/12of work two men can do =1hour.
1 of work two men can do =12/5
2/3 of work two men can do=12/5*2/3= 1hour 36 mins
Hope it help
