Answer:
Rs.75
Step-by-step explanation:
Amount (A) = Rs.915
Let the principal be P.
Simple Interest (SI) = Rs.(915-P)
Rate (R) = 11/4 %
Time (T) = 8 years
SI = PRT/100
915 - P = P × 11/4 × 8 × 1/100
915 - P = P × 11/50
50 (915 - P) = 11P
4575 - 50P = 11P
4575 = 11P + 50P
4575 = 61P
P = 4575 ÷ 61
P = 75
Hence, the sum is Rs.75

Step-by-step explanation:
Sum in 3 yrs = 815
Sum in 4 yrs= 854

So sum = 815–117=698
