Question

if 14 compositors can compose 70 pages of a book in 5 hours, how many compositors will compose 100 pages of this book in 10 hours?​

Answer 1

14 compositors compose 70 pages in 5 hours.

So,

14 compositors will compose 70/5 that is 14 pages of book in 1 hour.

So 1 compositor will compose 1 page of book in 1 hour.

Now, required compositors = no. of pages/no. of hours = 100/10 = 10 compositors

Answer 2

Answer:

10 compositors will compose 100 pages of this book in 10 hours

Step-by-step explanation:

14 compositors can compose 70 pages of a book in 5 hours

We are supposed to find  how many compositors will compose 100 pages of this book in 10 hours?​

Formula : $\frac{m_1 \times h_1}{w_1} =\frac{m_2 \times h_2}{w_2}$

$w_1=70\\m_1 =14\\h_1=5\\w_2=100\\h_2=10\\m_2=?$

Substitute the values in the formula

$\frac{14 \times 5}{70} =\frac{? \times 10}{100}$

$\frac{14 \times 5 \times 100}{70 \times 10} =?$

$10=?$

Hence 10 compositors will compose 100 pages of this book in 10 hours
