hi
12 workers take 6 days to complete work
no. of days taken by 15 workers=!
12/6=15/x
x=12*6/15
x=4.5
∴15 workers take 4 and half days i.e. 4.5 days to complete work
12 workers take 6 days to complete work
no. of days taken by 15 workers=!
12/6=15/x
x=12*6/15
x=4.5
∴15 workers take 4 and half days i.e. 4.5 days to complete work
jrc:
Acctually unitary method can not be used here as the relation is not direct instead the inverse of unitary method is used I.e, (12*6)/15= 4.8
