Question

What is the sectorial angle corresponding to the money spent by the family in savings, clothing and others together?

• A. ${144}^{\circ }$
• B. ${162}^{\circ }$
• C. ${108}^{\circ }$
• D. ${180}^{\circ }$

Answer 1

The correct option is B ${162}^{\circ }$

$\Rightarrow$ Percentage of money spend in saving $=15\%$

$\Rightarrow$ Percentage of money spend in clothing $=10\%$

$\Rightarrow$ Percentage of money spend in other things $=20\%$

$\Rightarrow$ Total percentage of money spend in saving, clothing and other things $=15\%+10\%+20\%=45\%$

$\Rightarrow$ The sectorial angle corresponding to money spend in savings, clothing and other together $=45\%of{360}^o$

$=\frac{45}{100}\times {360}^o$

$={162}^o$
