Total amount accumulated over time, including the principal and interest.
\[
A = P + SI
\]
Principal (P)
P:
Initial amount of money invested or borrowed.
\[
P = \frac{100 \times SI}{R \times T}
\]
Rate of Interest (R)
R:
Rate of interest per annum, expressed as a percentage.
\[
R = \frac{100 \times SI}{P \times T}
\]
Time (T)
T:
Duration for which the money is invested or borrowed.
\[
T = \frac{100 \times SI}{P \times R}
\]
