Given:

↬amount = Rs. 5290

↬time = 12 years

To Find:

➺rate of interest

Solution:

here we use the formula

 \sf \: Amount =  \frac{  P \times  T \times  R }{100}  \\  \\ \sf 5290 =  \frac{40{ \cancel{00}} \times 2 \times x}{1 {\cancel{00} }} \\  \\  \sf \: 5290 = {80 \times x} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \sf x =  \frac{5290}{80}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \sf \: rate \: of \: intrest = 66.125\%
