- ans is 60mins
gn:
A+B=91/24)
A=(1/40)
(1/40)+B=(1/24)
B=(1/60)
=>B=60mins - 12 years agoHelpfull: Yes(13) No(1)
- assume A's work is =w1 and B's work is=w2
so
w/w1=40 and w/(w1+w2)=24 now we have to calculate w/w2=?
so by solving both equations we get w/w2 as=60 min so
B's time = 60 min - 12 years agoHelpfull: Yes(4) No(0)

- 1/x+1/y=xy/x+y=====>24 min.
1/40+1/y=1/24
1/y=1/40-1/24==2/120===>1/60
So 2nd person can alone do that work in 60 days - 9 years agoHelpfull: Yes(0) No(0)
- (1/24-1/40) = (40-24)/40*24= 60 min
