initial number= 2000

first day -   2000(.3) =600 will be eliminated
     therefor; 2000-600 = 1400, can proceed to the next round.

second day- 1400(.3) =420 will be eliminated
    therefor; 1400-420= 980, can proceed to the next round

third day- 980(.3) =294 will be eliminated
    therefor; 980-296= 686,can proceed to the next round

fourth day- 686(.3)=205.8 equivalent to 206 will be eliminated
     therefor; 686-206=480 can proceed to the next round

the final answer is 480, will be present in the start of the 5th day. .
