Answer:
R0
Explanation:
Given the following data;
Principal, P = R625
Time, t = 1 year
Rate, r = 10% = 10/100 = 0.1
To find compound interest;
Substituting into the equation, we have;



A = 687.5
Therefore, C.I = A - P
C.I = 687.5 - 625
C.I = 62.5
To find the simple interest;


S.I = 62.5
Now to find the difference;
Difference = C.I - S.I
Difference = 62.5 - 62.5
Difference = R0
