A man got Rs. 130 less, as simple interest, when he invested Rs. 2000 ...

Given Data:
- Principal amount for first investment (P1) = Rs. 2000
- Principal amount for second investment (P2) = Rs. 2250
- Time duration (t) = 4 years
- Simple interest difference = Rs. 130

Calculating Simple Interest:
- Simple Interest = P * R * T / 100

Calculating Simple Interest for First Investment:
- SI1 = 2000 * R * 4 / 100

Calculating Simple Interest for Second Investment:
- SI2 = 2250 * R * 4 / 100

Given Difference in Simple Interest:
- SI2 - SI1 = 130
- (2250 * R * 4 / 100) - (2000 * R * 4 / 100) = 130
- 90R = 130
- R = 130 / 90
- R = 1.44

Converting Rate of Interest to Percentage:
- Rate of Interest = 1.44 * 100
- Rate of Interest = 144%

Therefore, the rate of interest is 13%.
