What is the value of the expression "the amount of One naira Per annum in n' years multiplied by Two naira"?

Step 1: Interpret the financial terms.
The phrase "amount of One naira Per annum" is interpreted as the total amount (principal + interest) when the principal is 1 naira and the annual interest rate is 100% (or 1). We will assume simple interest as it is not specified otherwise. The formula for simple interest amount is $A = P(1 + RT)$, where $P$ is the principal, $R$ is the annual interest rate, and $T$ is the time in years.
In this case, $P = 1$ naira and $R = 1$ (for 100% per annum).

Step 2: Calculate each component of the expression.

• The first part is "the amount of One naira Per annum in $n'$ years". Using the simple interest formula with $P=1$, $R=1$, and $T=n'$: $$$$
