Question

principal=5000 amount = 6450 time65days find rate

Answer 1

$s.i = amount - principle \\ = > 6450 - 5000 \\ = > 1450$
Principle=5000
time=65/365year
s.i=1450
$= > rate = \frac{s.i \times 100}{p \times t} \\ = > \frac{1450 \times 100 \times 365}{65 \times 5000}$
after multiplication the answer will be
$162.85$
