a boy won a prize £25which he deposited into a bank at an intrest rate of 6%. How much interest did he recive at the end of the year
that would be 25£x1.06 for a whole year of profit. But it depends on how long has it been in the bank. If you would say six months, it would be 25£x1.066/12
25 x 6/100 =1.50 pounds - interest for 1 full year.
