Find the average daily expenditure of a man in 2017, who spent Rs. 76310 in the first-half year and Rs. 87940 in the last?
Rs. 450
To find the average daily expenditure for the man in 2017, we first need to calculate the total amount he spent during the entire year. The total expenditure is the sum of the expenditure in the first half and the expenditure in the last half of the year.
The expenditure for the first half year was Rs. 76310.
The expenditure for the last half year was Rs. 87940.
Total Expenditure = Expenditure in first half + Expenditure in last half
Using the given values:
$\text{Total Expenditure} = \text{Rs. } 76310 + \text{Rs. } 87940$
$\text{Total Expenditure} = \text{Rs. } 164250$
So, the total amount spent by the man in 2017 was Rs. 164250.
The year 2017 was not a leap year. A standard year has 365 days.
Number of days in 2017 = 365 days.
The average daily expenditure is found by dividing the total expenditure for the year by the total number of days in the year.
$\text{Average Daily Expenditure} = \frac{\text{Total Expenditure}}{\text{Number of Days in 2017}}$
Substitute the values we calculated:
$\text{Average Daily Expenditure} = \frac{\text{Rs. } 164250}{365 \text{ days}}$
Now, we perform the division:
$164250 \div 365$
Let's calculate the result:
$164250 \div 365 = 450$
The average daily expenditure is Rs. 450.
The average daily expenditure of the man in 2017 was Rs. 450.
