A naval detachment has enough rations to feed fifteen people for 8 days.
If five more people join the detachment, for how many fewer days will the rations last?
:
15 * 8 = 120 man-days of food available
let d = no. of days when there are 20 men
20d = 120
d = 120/20
d = 6 days or 2 days fewer with the 5 added men
