Question

A 20-dirham note is 13 cm long. How many such notes need to be placed one after the other without overlapping to cover a length of 1 1 2 m?

Answer 1

861 (approx)

Explanation:

It is given that there is a note of 20 dirham. The 20 dirham note is 13 cm long. And we have to place the 20 dirham notes to cover a length of 112 m without overlapping the notes.

We know that :

100 cm = 1 m

∴ 13 cm = 0.13 m

In order to cover a length of 112 m, we have to divide 112 by 0.13, i.e.

`$=(112)/(0.13)$`

`$=(11200)/(13)$`

= 861 (approx)
