Correction is the question: 6\frac{1}{2}%% = 6.5%

Answer:

Amount to be repaid is $335798.833

Step-by-step explanation:

Amount of loan = $332,200

Rate of interest = 6.5%

time =  2months = 2/12 = 1/6 years

The amount of interest is simple interest

SI = \frac{P * R * T}{100}

    =\frac{ 332200 * 6.5 *1 }{100 * 6}

    = $3598.833

Final amount to be repaid = 332200+ 3598.833

                                            = $335798.833
