3. P = float(int("Enter principal amount: "))
R = float(input("Enter rate of interest: "))
T = float(input("Enter time in years: "))
SI = (P * Q * R) / 100
print(f"The simple interest is {SI}")
Ans. P = float(input("Enter principal amount: "))
R = float(input("Enter rate of interest: "))
T = float(input("Enter time in years: "))
SI = (P * R * T) / 100
print(f"The simple interest is {SI}")
