Assuming its a simple interest peoblwm.
Amount in 3Yrs = 550
Amount i. 5 yrs = 650
Simple interest earned for 2yrs = 650-550 = 100
Interest earned for 1yr = 100/2 = 50
Interest earned for 3yrs = 50 * 3= 150
Principle = 550 - 150 = Rs.400
Amount in 3Yrs = 550
Amount i. 5 yrs = 650
Simple interest earned for 2yrs = 650-550 = 100
Interest earned for 1yr = 100/2 = 50
Interest earned for 3yrs = 50 * 3= 150
Principle = 550 - 150 = Rs.400
