# A piece of ribbon folded five times is placed along a 30 cm long measuring scale as shown in figure.

The length of the ribbon is between

$(a)$. 1.15 m â€“ 1.25 m

$(b)$. 1.25 m â€“ 1.35 m

$(c)$. 1.50 m â€“ 1.60 m

$(d)$. 1.60 m â€“ 1.70 m"

Given: A ribbon folded 5 times

To find: The length of the ribbon

Solution:

The folded ribbon lies between 2 cm and 27.5 cm. So its length is the distance between 2 cm and 27.5 cm.

It is 27.5 - 2 = 25.5 cm.

The length of the folded ribbon is nearly 25.5 cm.

Since it is folded 5 times, the total length of the ribbon is about $5\times25.5\ cm=127.5\ cm$

$=1.275\ m$ [As $1\ m=100\ cm$]

â€ŠSo, option $(b)$ 1.25 m-1.35 m is correct.
