Answer 2

Answer:

P= 1500

si= 300

Step-by-step explanation:

if it is the rate is simple Interest

$amount = p + s.i =p + \frac{p \times r \times t}{100} \\ \\ amount \: = p \times \: (1 + \frac{r \times t}{100} ) \\ = > 1800 = p \times (1 + \frac{10 \times 2}{100} ) \\ = > 1800 = p \times (1 + \frac{1}{5} ) \\ = > 1800 = p \times \frac{6}{5} \\ = > p = \frac{1800 \times 5}{6} \\ = > p = 600 \times 5 = 1500$

NOW ,

$interest \: = \frac{p \times r \times t}{100} \\ = \frac{1500 \times 10 \times 2}{100 } \\ = 15 \times 10 \times 2 \\ = 300$
