Answer 2

Given :

In a library 126 books require a shelf length of 3.78m.

To Find:

How many books would occupy s shelf length of 4.6 m.

Solution:

No. of books required for a shelf length of 3.78 m = 126

No. of books required for a shelf length 1 m =$\frac{126}{3.78}$

No. of books required for a shelf length of 4.6 m = $\frac{126}{3.78} \times 4.6=153.33$

So,No. of books required for a shelf length of 4.6 m =153

Hence 153 books would occupy shelf length of 4.6 m.
