Answer:
The sum Bello deposited was #750.
To calculate this, we use the formula for simple interest:
I = Prt
Where I is the interest, P is the principal (the amount deposited), r is the rate of interest (8% per annum), and t is the time (3 years).
We can rearrange the formula to solve for P:
P = I/rt
Substituting the given values, we get:
P = 806/0.08(3)
P = 750
Therefore, the sum Bello deposited was #750.
