Question

What degree measure is shown by the sketch pen?

• A. ${15}^o$
• B. ${18}^o$
• C. ${20}^o$
  
• D. ${22}^o$

Answer 1

Answer: (B)

${18}^o$

$Items$	$Cost$ $\left(in\%\right)$
$Sketch-pen$	$5\%$
$Compassbox+slate$	$15\%$
$Notebook$	$40\%$
$Bag$	$30\%$
$Water-bag$	$10\%$

$\Rightarrow$ Cost price of sketch pen ( in $\%$) $=5\%$

$\Rightarrow$ Cost price of sketch pen in degree $=\frac{5}{100}\times {360}^o$

$={18}^o$
