If 29compositors can compose 65 pages of a book in 9 hrs,how many compositors will compose 98 pages of this book in 17 hrs

Answer:_______________

If 20compositors can compose 55 pages of a book in 10 hrs,how many compositors will compose 86 pages of this book in 17 hrs

Answer: 18

SOLUTION 1 :

Soln :

Number of compositors	Number of hrs	Number of pages
20	10	55
	17	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 10 to 17 & the No of compositors decreases .

it is in inverse variation.

The multiplying factor = $\frac{10}{17}$

x = $\frac{86}{55}$ x $\frac{10}{17}$ x 20

= 1.56363636364 x 0.588235294118 x 20
