You can put this solution on YOUR website! if 24 adult can finish a work in 16 days and 16 children can finish the same work in 48 days then how much time it would take one adult and 1 child to finish the work?
:
We know it takes
24*16 = 384 man-days to do the job
or
16*48 = 768 child-days (twice as many as man-days)
Therefore:
2 child-days = 1 man-day
:
"then how much time it would take one adult and 1 child to finish the work?
let d = no. of days for 1 child and 1 man to do the job
:
1 child and 1 man = 1.5 man
:
1.5d = 384
d =
d = 256 days for one man and one child to do the job
