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

(d) 40%

Sector angle corresponding to recreation 

= 360° – (72°+ 90° + 54°) 

= 360° – 216° 

=144° 

∴ % age expenses incurred on account of recreation 

= \(\bigg(\frac{144°}{360°}\times100\bigg)\) % = 40%
