Answer:
Hence, the sum is 3200.
Step-by-step explanation:
We are given
Amount (A) = 3920
Rate (R) = 7.5%
Time (T) = 3 years
The formula for simple interest (S.I.) is
(P*R*T)/100
A = S.I. + P
3920 = {(P*R*T)/100} + P
3920 = {(P*7.5*3)/100} + P
3920 = {(P*22.5)/100} + P
Here we will take L.C.M of 100 and 1
3920 = (22.5P + 100P)/100
3920*100 = 122.5P
392000/122.5 = P
P = 3200
Hence, the sum is 3200.
