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
