Question

If one edge of a $6$-inch ruler is to be marked in $\frac{1}{10}$ inch units, how many marks will there be on the edge including the $0$ and $6$ inch marks?

• A. 59
• B. 60
• C. 61
• D. 62

Answer 1

Answer: (C)

61

In a ruler for $1$ inch there will be $10$ marks.

$\frac{1}{10},\frac{2}{10},\frac{3}{10}.....$

$\therefore$ in $6$ inch there will $=$ $10\times 6=60$ marks

For the beginning point '$0$' there is $1$ mark.

Total Marks $=60+1=61$
