Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of basic alzebra and ratio will be used to solve this question,

Given :

The number of students are $420$ and the provision is for these number of students is for $20$ days. $180$ more students joined the camp after that.

To Find:

We have to find the days for which the provision will be lasted if $180$ more students join.

Solution:

In this case, there is an inverse relationship between the number of days and the number of students because, as the population grows, the maximum number of days during which there will be enough provision falls.

Consider the number of student is $x$ and the number of days is $y$ .

The equation which is inverse can be written as $x_{1} y_{1} =x_{2} y_{2}$

Here $x_{1} =420$ , $y_{1} =20$ and the value of $x_{2} =420+180=600$

The value of $y_{2} =\frac{420 \times 20}{600} =140$.

The provision will last for $140$ days.
