whatbis the simple interest on #75 for 4 years at 2¹/² per annum

Answer 1

The simple interest on #75 for 4 years at 2¹/₂% per annum is:

I = (P * R * T) / 100
where:
I = interest
P = principal amount (the initial amount borrowed or invested) = #75
R = annual interest rate = 2¹/₂%
T = time in years = 4

I = (75 * 2.5 * 4) / 100
I = 7.50

Therefore, the simple interest on #75 for 4 years at 2¹/₂% per annum is #7.50.
