Question

It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?

Answer 1

Answer: 22 minutes

Step-by-step explanation:

Since, if $x_1$ people take $n_1$ days for doing $w_1$ work while  $x_2$ people take $n_2$ days for doing $w_2$ work,

Then,

$\frac{x_1\times n_1}{w_1}=\frac{x_2\times n_2}{w_2}$

Here, $x_1 = 10$, $n_1=22\text{ minutes}$, $w_1=10$ $x_2=14$  and $w_2=14$,

By substituting these values in the above equation,

We get,

$\frac{10\times 22}{10}=\frac{14n_2}{14}$

$\implies \frac{2200}{10}=n_2$

$\implies 22=n_2$

Hence, the time taken by 14 workers making 14 walls is 22 minutes.

Answer 2

220pm=10w  (people*minutes)

w=22pm

14w=308pm

308pm/14p=22m

So it would take 22 minutes for 14 people to paint 14 walls.
