63 is the right answer..
here is the clear blueprint for it!!!
let : total = X
1st person takes : p1 = (X/2) + (1/2) = Let it be A
2nd person takes : p2 = (X-A)/2 + (1/2) = Let it be B
3rd person takes : p3 = (X-B)/2 + (1/2) = Let it be C
4th person takes : p4 = (X-C)/2 + (1/2) = Let it be D
Now D = 3. (remain bread)
from 4th equation.., = (X-C)/2 + (1/2) = D = 3
substitute C from 3rd eqn., B from 2nd eqn., A from 1st eqn.. and ...WALLA... get ur answer as 63.
Example :
Out of 63,
Net Total = 63
1st person takes 31.5 and 0.5
Net Total = 31
2nd person takes 15.5 and 0.5
Net Total = 15
3rd person takes 7.5 and 0.5
Net Total = 7
4th person takes 3.5 and 0.5
Net Total = 3
which is the remaining bread..
(0.5 means 'half a bred')
