  1. 1500 men at 2Kg/man day ---> 3000 Kg needed per day

    1200 *2.4 Kg/man day *25 days = 72,000 Kg availablee

    3000 * number of days = 72,000
    so
    days = 24 days

  2. The number of men increases by a ratio 1500/1200 = 5/4, so the food would last 4/5 as long if the same rations are maintained. However, since the rations are being reduced by a ratio 2000/2400 = 5/6 , the food will last 4/5 * 6/5 as long, or (24/25)*25, which is 24 days.
