Question

principle=3000
rate=40%
year= 6
what is the SI
and the amount

Answer 1

the formula of finding SI(simple interst) Principle x rate x time / 100
$\frac{3000*40*6}{100}$
now solve it
30x40x6=7200
SI = 7200
now, formula of amount is
a=si+p
a=7200+3000
a= 10200

Answer 2

SI = P×R×T/100
= 3000×40×6/100
=30×40×6
=7200
AMOUNT = P + S.I.
= 3000 + 7200
= 10200
