Question

There is a provision for 150 men for 45 days in a
fort. After 10 days 25 men leave the fort. How long
the provision will last at the same rate ?​

Answer 1

Answer:

42 days

Step-by-step explanation:

After 10 days : 150 men had food for 35 days

Suppose 125 men had food for x days

If the no. of men decrease then the no. of days the provision will last will increase or vice-versa

So, this is a case of inverse variation

x*y = k (constant)

125*x = 150*35

x = 150*35/125

x = 42 days
