Step-by-step explanation:
Amount = 21296
Term = 3 Years
Rate p.a = 10%
CI Amount formula = P(\frac{100+R}{100} )^3P(
100
100+R
)
3
\begin{gathered}21296=P(\frac{110}{100})^3\\\end{gathered}
21296=P(
100
110
)
3
\begin{gathered}\frac{21296}{P}=(\frac{110}{100})^3\\\end{gathered}
P
21296
=(
100
110
)
3
\frac{21296}{P}=\frac{1331}{1000}
P
21296
=
1000
1331
\frac{21296}{P}=\frac{1331*16}{1000*16} (as 1331 * 16 = 21296)
P
21296
=
1000∗16
1331∗16
(as1331∗16=21296)
\frac{21296}{P}=\frac{21296}{16000}
P
21296
=
16000
21296
∴ Principle = 16000
