Question : At what rate percent per annum simple interest 66000 amount to 72720 in 2 years?

Solution :

A = 72720

P = 66000

SI = 72720-66000

= 6720

T = 2 years

R = ?

$R = (\frac{SI ×100}{P×T} )\% \\ \: \: \: \: \: =( \frac{6720 \times 100}{66000 \times 2 }) \% \\ \: \: \: \: \: = \frac{168}{33} \% \\ \: \: \: \: \: = 5 \frac{ 3}{33} \%$
