___________________________

We know that,

Simple Interest = ( Principal × Rate × Time ) / 100

Simple Interest = ( 8000 × 12 × 4 ) / 100

Simple Interest = 384000 / 200

Simple Interest = 3840

Simple Interest = ₹3840

FORMULAS

Simple Interest = ( Principal × Rate × Time ) / 100

Simple Interest = Amount - Principal

Principal = Amount - Simple Interest

Amount = Principal + Simple Interest

$\bf Amount = Principal \times ( 1 + \frac{r}{100} )^{n}$

$\bf Amount = Principal \times ( 1 + \frac{r}{n} )^{nt}$
