Question

garrison of 800 men had provision for 39 days. How many days would the food last

if another 500 men joined them?​

Answer 1

it is inverse proportion.

so inverse proportion is

Y= k/x

k= x × y

let the no.mens be x

let the no.days be y

k = 800 × 39 = 31200

k = 31200 ( k ) is constant of the variable.

our new x is 800 + 500 = 1300

y = k/x

y = 31200/1300

y= 24

24 days the food will last if 500 more men's join 800 men's.
