- 24 men*18 days=2days*24men+xdays*32men
x=12 - 11 years agoHelpfull: Yes(19) No(0)
- 1men1day work=1/432
24men2day wrk=1/18*2=1/9
remaining wrk=(1-1/9)=8/9
32men 1 day wrk=1/432*32=2/27
8/9 wrk done by them in(27/2*8/9)=12
option A is correct - 11 years agoHelpfull: Yes(6) No(0)
- ans is 10 days
24 men mens 1days wrk=1/18
1 men 1days wrk=1/18*24
they worked for two dyas hence they =2*1/18=1/9
8/9 of wrk is lft
nw 32 mens one day wrk is 32/18*24=4/36
4/36 of wrk= 1 day
8/9 of wrk=8/9*36/4=8days
8days + 2days already taken=10days - 11 years agoHelpfull: Yes(2) No(6)
