Question

Rs 3000 for 5 years at 6% p. a.

Answer 1

Si=3000*5*6/100=900
Si=p*r*t

Answer 2

net amount = 3000/-
intrest per annum = 6%
6% of 3000 is
$\frac{6}{100} \times 3000 \\ = 180$
total amount of intrest in 5 year = 180×5
= 900/-
total amount after 5 year =
net amount + intrest
3000+900 = 3900/-
