Amount after 3 years = Rs 815.
Amount after 4 years = Rs 854.
Formula Used:
Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)
Amount (A) = Principal (P) + Simple Interest (SI)
Calculation:
Interest for 1 year = Rs 854 - Rs 815 = Rs 39
Interest for 3 years = 39 × 3 = Rs 117
Principal (P) = Rs 815 - Rs 117
Principal (P) = Rs 698
The sum invested is Rs 698.
