Answer 1

Step-by-step explanation:

FORMULA :

$amount = p \: {(1 + \frac{rate \: of \: interest}{100})}^{n}$

• P = principle sum
• n = time

substitute the values

• amount = 2508.80
• rate of interest = 12%
• n = time = 2 years

$2508.80 = p \: {(1 + \frac{12}{100}) \: }^{2} \\ 2508.80 = p \: ( { \frac{100 + 12}{100} )}^{2} \\ 2508.80 = p \: {( \frac{112}{100} )}^{2} \\ p \: = \frac{2508.8}{ ({ \frac{112}{100} )}^{2} } \\ p \: = \frac{2508.80}{ (\frac{112 \times 112}{100 \times 100} )} \\ p = \frac{(2508.80 \times 100 \times 100)}{112 \times 112} \\ p = 2000$
