Amount deposited = 15000
Interest for first 6 months = 15000*(10 percent * 6/12)
= 15000*0.05= 750
Total amount after 6 months = 15000 + 750 = 15750
Interest for next 6 months = 15750 * (12 percent * 6/12)
= 15750*0.06=945
Total amount at the end of year= 15750+945=16695
Amount withdrawn = 16695/2=8347.5
Therefore amount remaining in the bank = 8347.5 ANS
