Answer»

A bank offers 5% compound interest per half year. A customer deposits RS. 4800 each on 1st JANUARY and 1st July of a year.

Compound interest for first 6 months = Rs. 4800 × [(1 + (5/200)) - 1] = Rs. 120

Principal amount for next 6 months = Rs. 4800 + 4800 + 120 = Rs. 9720

So, the compound interest for last 6 months = Rs. 9720 × [(1 + (5/200)) - 1] = Rs. 243

∴ The total interest GAINED = 120 + 243 = Rs. 363.
