Question

The following are the expenses of a household.

$\begin{array}{cc}\text{Items}& \text{Expenditure (in}₹)\\ \text{Food}& 4000\\ \text{Clothing}& 2000\\ \text{Rent}& 1500\\ \text{Education}& 1500\\ \text{Miscellaneous}& 1000\end{array}$

When drawing a pie – chart, the central angle for money spent on education will be ____ .

• A. ${72}^o$
• B. ${54}^o$
• C. ${144}^o$
• D. ${36}^o$

Answer 1

The correct option is B ${54}^o$

$\text{Total expenditure is}:$
4000 + 2000 + 1500 + 1500 + 1000 = ₹10,000

Central angle for money spent on education is
$=\frac{\text{expenditure on education}}{\text{total expenditure}}\times {360}^o$

$=(\frac{1500}{10000}\times {360}^{\circ })={54}^{\circ }$
