required data:-

1) principal=1200 ruppes

2)time=1/2 years (6/12=1/2)

3) rate of interest=7/2%

To solve the sum we use the formula of simple interest :-

Formula of simple interest = principal ×time ×rate÷ of interest /100

=> 1200×1/2×7/2/100ruppes

=>21 ruppes

$simple \: interest = \frac{principle \times time \times rate \: of \: interest}{100}$

$time = \frac{interest \times 100}{principle \times rate \: of \: interest}$

$rate \: of \: interest = \frac{interest \times 100}{principle \times time}$

$principle \frac{interest \times 100}{rate \: of \: interest \times time}$
