Step-by-step explanation:
5more days
Let us say that a soldier eats 'n' units of food in a day.
Total ration available = 100 soldiers * 10 days * n = 1000n
In 2 days, 100 soldiers would consume = 100n*2 = 200n
Remaining food = 1000n - 200n = 800n
Number of soldiers = 100 + 60 = 160
Amount of food these soldiers will eat in a day = 160n
Number of days the food will last = 800n / 160n = 5 days
