Question

if 15 bottles of water are needed for 7 men for 2 days how many bottles are required for four men for seven days​

Answer 1

Answer:29 bottle

Step-by-step explanation:

Answer 2

For seven days,four men need 30 bottles.

Given data :

For 2 days 7 men need 15 bottles.

• Now,to calculate the number of required bottles for the given days and men,we have to first calculate the bottles required for 1 man in 1 day.

So,

In 2 days 7 men need = 15 bottles

In 1 day 7 men need = 15/2 bottles ( directly proportional)

In 1 day 1 man needs = 15/2×7 = 15/14 bottles (directly proportional)

Now,we have to calculate the bottles needed for four men in seven days are :

In 1 day 1 man needs = 15/14 bottles

In 7 days 1 man needs = 15×7/14 = 15/2 bottles (directly proportional)

In 7 days 4 men need = 15×4/2 = 30 bottles ( directly proportional)

So,for 7 days 4 men need 30 bottles. (Answer)
