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 ratio of the amount spent by the family on medicine to the amount spent on groceries?

A. 1 : 2

B. 13 : 21

C. 3 : 5

D. 11 : 23

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 medicine) : (Amount spent on groceries)

\begin{aligned} = (45800 \times \frac{11}{100}) : (45800 \times \frac{23}{100}) \\ = 11 : 23 \end{aligned}
