Answer 2

Heya!!✋

Here is your answer.
----------------——---------—–------------

50 men eat stock of food in 40 days

1 man eat stock of food in (40×50) days

80 men eat stock of food in (2000÷80) days
=> 25 days

[ Here the number of men and the days are in proportion.

→ If the number of men increase, the less time will be needed.

→ If the number of men decrease, the more time will be needed. ]

Hope it will help, friend. :)
