Given Data:
Simple Interest = Rs. 78
Time = 2 ¼ years
Rate = 2 2/3 %

To Find:
Principal Amount (Sum)

Formula:
Simple Interest (SI) = (Principal * Rate * Time) / 100

Calculation:
- Convert time to a fraction: 2 ¼ years = 9/4 years
- Convert rate to a fraction: 2 2/3 % = 8/3 %

Substitute the values:
78 = (Principal * 8/3 * 9/4) / 100
78 = (72 * Principal) / 1200
78 = 6 * Principal / 100
6 * Principal = 7800
Principal = 1300

Therefore,
The sum of money (Principal) is Rs. 1300.
