Question
There is enough food in a camp to last for 50 days if
each of the 80 soldiers present at the camp eat 2 times a day. After 20 days, 30 soldiers left the camp and remaining ate only once a day. For how many days (from start) will the food last?Solution
Let the eating capacity of each soldier be 'x' units So, total food at the camp = (50 X 80 X 2 X x) = '8000x' units And food remaining after 20 days = 8000x - (20 X 80 X 2 X x) = '4800x' units So, required time = 4800x ÷ (x X 1 X 50) = 96 days So, the food will last for a total of 96 + 20 = 116 days
