The ration will last for 5 days.
Step-by-step explanation:
Given : In an army camp ration available for 100 soldier for 10 days after 2 days 60 soldier joined.
To find : How many days ration will last?
Solution :
Let soldier eats 'x' units of food in a day.
Total ration available for 100 soldiers for 10 days.
i.e. 100\times 10\times x=1000x100×10×x=1000x
In 2 days, 100 soldiers would consume 100x\times 2 = 200x100x×2=200x
Remaining food is 1000x - 200x = 800x1000x−200x=800x
Number of soldiers = 100 + 60 = 160
Amount of food these soldiers will eat in a day is 160x.
Number of days the food will last is \frac{800}{160}=5
160
800
=5
Therefore, The ration will last for 5 days
