Question

In a library, 136 copies of an encyclopedia require
a shelf length of 3.4 m. How many copies of the
encyclopedia book would occupy a shelf length of
5.1 m?​

Answer 1

Answer:

Let x be the number of copies that would occupy a self-length of 5.1m.

Number of copies 136 x

Length the self ( in m ) 3.4 5.1

Since, the number of copies and the length of the shelf are in direct variation.

∴

x

136

=

5.1

3.4

⇒ 136×5.1=x×3.4

⇒ x=

3.4

136×5.1

⇒ x=204

∴ 204 copies will occupy a shelf of length 5.1m.
