Question

What is the length of the given pencil in cm?

• A. 10
• B. 11
• C. 10.5
• D. 11.5

Answer 1

The correct option is C 10.5

The tip of the pencil coincides with the 5${}^{th}$ small division after 11 cm.
There are 10 small divisions between any two major divisions.
So we can say that the length of one small division = 0.1 cm
Therefore, the length of 5 small divisions = 0.1 $\times$ 5
= 0.5 cm
We can see that the length of the pencil runs from 1 cm to 11.5 cm.
$\therefore$ The length of the pencil = 11.5 - 1
= 10.5 cm
