Answer 2

Answer:

$Principal (P) = Rs \: 20000$

Step-by-step explanation:

Let Principal = P

Amount (A) = Rs 20800,

Rate of interest (R) = 2% per annum

Time (T) = 2 years

$\boxed { P\left(1+\frac{RT}{100}\right) = A}$

$\implies P\left( 1+ \frac{2\times 2}{100}\right)= 20800$

$\implies P\left( 1+ \frac{1}{25}\right)= 20800$

$\implies P\left( \frac{25+1}{25}\right) = 20800$

$\implies P \times \frac{26}{25}=20800$

$\implies P = 20800 \times \frac{25}{26}= 20000$

Therefore,

$Principal (P) = Rs \: 20000$
