Question

The pie chart given below shows the expenses incurred and saving by a family in a month. What is the percentage of expenses incurred on account of recreation?

• A. $\frac{800}{17}$
• B. $20\%$
• C. $35\%$
• D. $40\%$

Answer 1

Answer: (D)

$40\%$

Sector angle corresponding to recreation
$={360}^o-({72}^o+{90}^o+{54}^o)$
$={360}^o-{216}^o$
$={144}^o$
$\therefore$ $\%$ age expenses incurred on account of recreation = $(\frac{{144}^o}{{360}^o}\times 100)\%=40\%$
