Question

The daily income of a vegetable vendor on five days was Rs 73, Rs 79, Rs 81, Rs 77 and Rs 75. What was his average daily income?

Answer 1

Total income of the vegetable vendor = Rs 73 + Rs 79 + Rs 81 + Rs 77 + Rs 75 = Rs 385
Total number of days = 5
Average daily income$=\frac{\mathrm{Total}\mathrm{income}\mathrm{of}\mathrm{the}\mathrm{vegetable}\mathrm{vendor}}{\mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{days}}$
$$\begin{gathered} =\mathrm{Rs}\frac{385}{5} \\ =\mathrm{Rs}77 \end{gathered}$$
