Answer 1

$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hello Friend}}}$

P = 1500
T = 7/2 years
A = 2655

So
Amount = P (1+ RT/100)
$2655 = 1500(1 + \frac{7 \times r}{2 \times 100} ) \\ \frac{2655}{1500} = 1 + \frac{7r}{200} \\ \frac{2655}{1500} - 1 = \frac{7r}{200} \\ \frac{2655 - 1500}{1500} = \frac{7r}{200} \\ \frac{1155}{1500} = \frac{7r}{200} \\ r = \frac{1155 \times 200}{1500 \times 7} \\ r = 22\%$
II Method for Solve this

SI= A - P = 2655 -1500
=1155
$r = \frac{100 \times si}{p \times t} \\ r = \frac{100 \times 1155}{1500 \times 3.5} \\ r = 22\%$
