Question

Principal =®5000 amount =®6450 and rate =12%

Answer 1

SI = A-P = Rs. 6450-5000 = Rs. 1450

$si = \frac{prt}{100} = > t = \frac{si \times 100}{pr}$

$t = \frac{1450 \times 100}{5000 \times 12} = \frac{29}{12} = 2.42$

Answer. Time is 2.42 years.

Hope it helps !!!

Answer 2

hey user........
$si = a - p = \frac{( p \times r \times t)}{100} \ \\ \: \: \: \: \: = 6450 - 5000 = \frac{5000 \times 12 \times time}{100} \\ \: \: \: \: \: = 1450 = \frac{5000 \times 12 \times time }{100} \\ time = 2.41 \: years$
HOPE IT HELPS
THANK YOU.
