6%
It shall be noted that value of $75000 on 7th year from now at different interest rate is:
| 0th Year | 7th Year | |
| 8% | 75000 | 128537 | 
| 12% | 75000 | 165801 | 
| 10% | 75000 | 146154 | 
| 6% | 75000 | 112772 | 
The value of $50000 on 7th year from now, given that it originates at 4th year from now, at different interest rate is:
| 4th Year | 7th Year | |
| 8% | 50000 | 62985.6 | 
| 12% | 50000 | 70246.4 | 
| 10% | 50000 | 66550 | 
| 6% | 50000 | 59550.8 | 
Thus, the total value at 7th year from now:
| Value of $75000 at 7th Year from Now | Value of $50000 at 7th Year from Now | Total | |
| 8% | 128536.8202 | 62985.6 | 191522.4 | 
| 12% | 165801.1056 | 70246.4 | 236047.5 |

| 6% | 112772.2694 | 59550.8 | 172323.1 | 
The value of $20000 at 7th year, given that is awarded every year from 7th year onwards till perpetuity at different interest rate is:
| Value of $20000 assuming perpituity | |
| 8% | 250000 | 
| 12% | 166666.6667 | 
| 10% | 200000 | 
| 6% | 333333.3333 | 
Thus, at 10%, value of donations at 212703.8 is closer to value of scholarship at 200000
Hence, 10% is the nearest rate of return for the invested money
