Answers
Given : town has provisions to last for 3 weeks.
Its populations is 22400
To Find : how many people must be sent away in order that the provision may last for 7 weeks.
Solution:
populations is 22400
provisions to last for 3 weeks.
Hence Provision = 22400 x 3 man weeks
Let say P people left
Then People = (22400 - P)
Provision last for 7 weeks
hence provision = (22400 - P) * 7 man weeks
22400 x 3 = (22400 - P) * 7
=> 3200 x 3 = 22400 - P
=> 9600 = 22400 - P
=> P = 22400 - 9600
=> P = 12800
12800 people have to leave
