1. Study the following pie-chart carefully and answer the questions that follow:
Degreewise Break-up of Expenditure of a Family in a month
Total Amount Spent In a Month = Rs. 45800.

What is the total amount spent by the family on Entertainment and Shopping together?

A. Rs. 9618

B. Rs. 13282

C. Rs. 13740

D. Rs. 11908

Solution:

Percentage Break-up of expenditure is:

\begin{aligned} Investments → (\frac{54}{360} \times 100) % \\ = 15 % \\ Commuting → (\frac{79.2}{360} \times 100) % \\ = 22 % \\ Shopping → (\frac{68.4}{360} \times 100) % \\ = 19 % \\ Groceries → (\frac{82.8}{360} \times 100) % \\ = 23 % \\ Medicines → (\frac{39.6}{360} \times 100) % \\ = 11 % \\ Entertainment → (\frac{36}{360} \times 100) % \\ = 10 % \end{aligned}

Amount spent on Entertainment and Shopping

\begin{aligned} = Rs. (45800 \times \frac{10 + 19}{100}) \\ = Rs. (45800 \times \frac{29}{100}) \\ = Rs. 13282 \end{aligned}
