Question 71

The given Bar Graph presents the data of annual income (A) and annual expenditure (B) of an IT officer in a multinational company during the years 2012 to 2016.

What was his average monthly savings (in ₹) in 2015 and 2016, taken together (correct to two decimal places)?

Solution

Annual income in 2015 = 9 lakhs

Annual expenditure in 2015 = 7.5 lakhs

Annual savings in 2015 = 9 - 7.5 = 1.5 lakhs

Annual income in 2016 = 10 lakhs

Annual expenditure in 2016 = 8 lakhs

Annual savings in 2016 = 10 - 8 = 2 lakhs

Average of annual savings in 2015 and 2016= $$\frac{1.5+2}{2}=175000$$

Monthly annual savings in 2015 and 2016 = $$\frac{175000}{12}= 14583.33$$
