Six workers can paint 4 houses in 8 days.
how many additional workers are needed if the job of painting 8 houses must be finish in 4 days?
:
Find how many man-days required for each house
= 12 man-days per house
then
12 * 8 = 96 man-days to paint 8 houses
:
let w = no. additional workers required
4(w+6) = 96
4w + 24 = 96
4w = 96 - 24
4w = 72
w = 72/4
w = 18 additional men required
