Answer 2

Step-by-step explanation:

Given that there is sufficient food for 500 scouts for 21 days

also Given that 250 more Scouts joined the camp

they asked us to find how long the food lasts for

so this is an inverse proportion because more is the number of scouts, lesser is the number of days for which the food lasts.

number of scouts = 500

number of days = 21

so after 250 scouts joined number of days becomes x

thus,

500×21=750×x

10500 = 750x

x= 10500/750

x= 14

.°. days last for 14 after 250 scouts joined
