Degree wise Break-up of Expenditure of a Family in a Month:
Total amount spent in a month = ₹45,800
What is the total amount spent by the family on Entertainment and Loan EMI together?
Solution
We have the degrees in the pie chart for all the expenditure categories. This can be used to identify the fraction of the total amount spent on that particular expense.
For instance, Investments has $$54^{\circ\ }$$. This means that of the total (which is $$360^{\circ\ }$$ ), the amount corresponding to 54 is spent in investments. The total given is 45800, so we have the amount spent on investments is $$\frac{54^{\circ\ }}{360^{\circ\ }}\times\ 45800=6870$$
Similarly the others are calculated and tabulated as follows:
So the total amount spent by the family on Entertainment and Loan EMI together is 4580+8702= 13282, which is option B.
