On the 1st day,a person earns rs 1,and spends none.On every subsequent day he earns twice the amount earned on previous day and spends half the amount earned on previous day .At the end of 10th day ,how much money is left with him..???

• total earnings for 10 days 1+2+4+8+16+32+64+128+256+512
  amount spent(in nine days) =.5+1+2+4+8+16+32+64+128
  amount left=(total earnings-total amount spent)=256+512-0.5=767.5
