Answer 2

your answer is given below.

let the principal be x.

$SI = \frac{p \times r \times t}{100} = \frac{x \times 2 \times 2}{100} = \frac{4x}{100} = \frac{x}{25}$

$Amount = SI+P \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{x}{25} + x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{x + 25x}{25} = \frac{26x}{25}$

According to question,

$\frac{26x}{25} = 20800 \\ x = \frac{20800 \times 25}{26} = 20000 \: rs$

so, Principal = 20000
