- 1 boy's 1 day work=1/25
1 men's 1 day work=1/32
8 mens 10 boys work=8/32+10/25===20/13
they can complete the work in 13/20 days ==1 7/13 ans D - 11 years agoHelpfull: Yes(17) No(6)
- A/to given details :
25 boys can do work in 1 day
32 men can do work in 1 day
So 25 boys = 32 men ; ==> 1 boy=32/25 men
Now 8men + 10 boy ==> 8+(32/25)*10 men
==> (104/5)men
As per given que 8 men can complete in 4 days so 104/5 men can complete in
required days = (8*4) * (5/104) = 1.73 days .
no options match but this is the way
