Answer 2

Given : 5 people cleared a plot of land in 15 days.

To find : The number of people that is needed to be hired to clear three times that plot in 5 days.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the required number of people)

Here, we will be using general arithmetic method.

So,

In 15 days 1 time the plot is cleaned by = 5 people

In 1 day 1 time the plot is cleaned by = 5 × 15 people

In 5 days 1 time the plot is cleaned by = (5 × 15)/5 people

In 5 days 3 times the plot is cleaned by = (5 × 15 × 3)/5 = 45 people

(This will be considered as the final result.)

Hence, 45 people is needed to be hired.
