Question

p=1800 r =12 , t= 25/2

Answer 1

here,
principal=1800
rate= 12%
time=25/2
simple interest= p×r×t/ 100
= 1800×12×25/ 100×2
= SI= 2700
so amount= SI + principal
=2700+1800
=₹4500

Answer 2

$= > i = \frac{p \times t \times r}{100} \\ \\ = > i = \frac{1800 \times \frac{25}{2} \times 12 }{100} \\ \\ = > i = 18 \times 25 \times 6 \\ \\ = > i = 18 \times 150 \\ \\ = > i = 2700$
