Question

if a canteen has a raw material of 10 days. for 200 persons. however, 60 people move away. how many days will it last away?​

Answer 1

The remaining people can use the same material for 14 days.

Given:

a canteen has a raw material of 10 days for 200 persons

60 people move away

To find:  

How many days will it last away

Solution:

Given 1 row of material 10 days for 200 persons

Here 60 persons were moved away

The remaining persons = 200 - 60 = 140

Let x be the number of days that 180 people can use the material

Here the number of people is decreased the number of days to use the material will be increased  

So we can conclude that number of days is inversely proportional to the number of people  

The relation between them can be represented as given below

=> 10 × 200 = 140 × x

=> x = 2000/140

=> x = 14.285 ≅ 14 days

Therefore,

The remaining people can use the same material for 14 days.
