Answer:
66 days
Step-by-step explanation:
Let us assume that one soldier eats 'n' units of food in a day.
Then, 330 soldiers will eat 330 x n times per day.
330 soldiers in 90 days will eat = 330 soldiers x 90 days x n = 29,700 n units of food
Total Food left after 20 days= 29700 n - (330 x 20 x n)
= 23,100 n
Now, for next 70 days there are 20 more soldiers i.e. 330+20=350 solders
Amount of food these soldiers will eat in a day = 350 n
Number of days the food will last = 23,100 n / 350 n = 66 days
