$\: \: \: \: \: \: \: \: \: \: \: principal = 1200$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: rate = 10\%$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: time \: = 2 \: year$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: s.i. = \frac{p \times r \times t}{100}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: s.i. = \frac{1200 \times 10 \times 2}{100}$
