in an army camp the provision for 20 people is 10 days what will be the food provision if 5 more people join the camp

9514 1404 393

  8 days

Step-by-step explanation:

Assuming the number of days is inversely proportional to the number of people, increasing the number of people by a factor of 25/20 = 5/4 will decrease the number of days by the factor 4/5.

  (4/5)(10 days) = 8 days

The provisions will last 8 days if 5 more people join the camp.

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
