If 30compositors can compose 60 pages of a book in 10 hrs,how many compositors will compose 82 pages of this book in 16 hrs

Answer:_______________

If 30compositors can compose 55 pages of a book in 7 hrs,how many compositors will compose 86 pages of this book in 18 hrs

Answer: 18

SOLUTION 1 :

Soln :

Number of compositors	Number of hrs	Number of pages
30	7	55
	18	86

Consider the compositors and pages

As the No of pages increase from 55 to 86 & theNo of compositors also increases.

It is in direct variation.

The multiplying factor = $\frac{86}{55}$

Consider the copmositors and hours .

As the No of hrs increases from 7 to 18 & the No of compositors decreases .

it is in inverse variation.

The multiplying factor = $\frac{7}{18}$

x = $\frac{86}{55}$ x $\frac{7}{18}$ x 30

= 1.56363636364 x 0.388888888889 x 30

= 18
