It is given that Anil borrows Rs 2 lakhs at an interest rate of
8% per annum, compounded half-yearly. It is also known that he repays Rs 10320 at the end of the first year and closes the loan by paying the outstanding amount at the end of the third year.
The total amount at the end of the first year is:
200000××=216320He repays 10320 rupees at the end of the first year, which implies the amount that remains unpaid at the end of the first year is 206000 rupees.
This unpaid amount will accrue interest for another two years.
Hence, the final amount at the end of three years is
206000××××=240990.86Hence, the accrued interest in these two years is
(240990.86−206000)=34990.86 rupees.
Hence, the total interest accrued over the three years
=(34990.86+16320)=51311 rupees.
The correct option is B
