answer me fast answer please​

Answer 1

Step-by-step explanation:

1. food for 400 men for 50 days

let the no. of required days be x

after 20 days 100 men leave the place

men left (400-100). 300

number of men = 400. 300

_______________________________

number of days. 30(50-20). x

hence it is a case of indirect variation

400×30 =300x

x= 400×30/300 =40

so, the food will last for 40 days

2. food for 200 men for 30 days

let the required days be x

number of men = 200. 150

__________________________

number of days= 30. x

hence it is a case of indirect variation

200×30 =150x

x = 200×30/150= 40

so the food will last for 40 days
