• B. Rs $2500$
• C. Rs $6000$
• D. Rs $9000$

Answer 1

The correct option is B

Rs $2500$

The explanation for the correct option.

Pie chart evaluation:

Understand that a pie chart is a circular statistical graphic that is divided into slices to illustrate numerical proportion.

Know that here the central angle of the sector representing his expenses on food and house rent on a pie chart is $60°$ and the total monthly salary is Rs $15000$

Therefore, the amount of money spent on food and house rent:

$\begin{array}{l}\frac{60°}{360°}\times 15000\\ =\frac{1}{6}\times 15000\\ =2500\end{array}$

Hence, the correct option is $\left(B\right)$ i.e. Rs $2500$.
