Question

If there are $10$ minor divisions between two major divisions, one major division representing $1^{\circ }C$, one minor division will be equal to:

• A. ${0.5}^{\circ }C$
• B. ${0.3}^{\circ }C$
• C. ${0.1}^{\circ }C$
• D. ${0.2}^{\circ }C$

Answer 1

The correct option is C ${0.1}^{\circ }C$

Given, one major division equals $10$ minor division.
Also, one major division $=1^{\circ }C$
$\therefore \text{1 minor division}$ $=\frac{1}{10}\times \text{one major division}$
$\Rightarrow \text{1 minor division}$ $=\frac{1}{10}\times 1^{\circ }\text{C}$
$\text{So,}\text{1 minor division}$ $={0.1}^{\circ }\text{C}$
