Total period = 60 daysAfter 15 days this period will be = 60 - 15 = 45 daysNumber of soldiers in the beginning = 80Number of soldiers join = 20 New number of soldiers = 80 + 20 = 100 Soldiers.Number of Soldiers Days 80 45 100 x More men, the food will last lesser days.This is an inverse proportion.80 : 100 : : 45 : xx = (80*45)/100x = 36 days15 days has already gone, so, the food will last for 15 + 36 = 51 days instead of 60 days.
