If 30compositors can compose 55 pages of a book in 5 hrs,how many compositors will compose 91 pages of this book in 18 hrs

Answer:_______________

If 29compositors can compose 60 pages of a book in 10 hrs,how many compositors will compose 90 pages of this book in 25 hrs

Answer: 17

SOLUTION 1 :

Soln :

Number of compositors	Number of hrs	Number of pages
29	10	60
	25	90

Consider the compositors and pages

As the No of pages increase from 60 to 90 & theNo of compositors also increases.

It is in direct variation.

The multiplying factor = $\frac{90}{60}$

Consider the copmositors and hours .

As the No of hrs increases from 10 to 25 & the No of compositors decreases .

it is in inverse variation.

The multiplying factor = $\frac{10}{25}$

x = $\frac{90}{60}$ x $\frac{10}{25}$ x 29

= 1.5 x 0.4 x 29

= 17
