Total expenditure in month = 31 x 68 = Rs. 2108
Total expenditure of first 15 days = 15 x 87 = Rs. 1305
Total expenditure for last 17 days = 17 x 51 = Rs. 867
Expenditure on 15th day = (1305 + 867) - 2108 = 64

Given:
- Average daily expenditure of an organization in August = Rs. 68
- Average daily expenditure for the first 15 days of August = Rs. 87
- Average daily expenditure for the last 17 days of August = Rs. 51

To find:
- Amount spent by the organization on the 15th of August

Solution:
Let's assume that the total expenditure of the organization in the month of August was 'x'.

- We know that the average daily expenditure for the first 15 days of August was Rs. 87. Therefore, the total expenditure for the first 15 days would be 15 x 87 = 1305.
- Similarly, the average daily expenditure for the last 17 days of August was Rs. 51. Therefore, the total expenditure for the last 17 days would be 17 x 51 = 867.
- Now, we can find the total expenditure of the organization in the month of August by adding the expenditure of the first 15 days and the last 17 days:
Total expenditure = 1305 + 867 = 2172

- We also know that the average daily expenditure for the entire month of August was Rs. 68. Therefore, the total expenditure for the entire month can be calculated as:
Total expenditure = 68 x 31 = 2108

- Now, we can find the amount spent by the organization on the 15th of August by subtracting the total expenditure for the last 17 days from the total expenditure for the entire month:
Amount spent on the 15th of August = Total expenditure - Expenditure for last 17 days
= 2108 - 867
= 1241

- Finally, we need to divide the amount spent on the 15th of August by the number of days in the month (31) to get the average daily expenditure on that day:
Average daily expenditure on the 15th of August = Amount spent on the 15th of August / 31
= 1241 / 31
= 40.03 (approx.)

Therefore, the amount spent by the organization on the 15th of August was Rs. 64 (approx.).
