Friends,
The Answer given by 'Gaurav Sharma' is correct and
the approach (bottom to top) suggested by 'Shailesh' is
good. But with minor correction we can arrive the solution
using this approach:
After 5th loot, No. of breads left = 3
after 4th loot, no. of breads left = (3+0.5)x2 = 7
after 3rd loot, no. of breads left = (7+0.5)x2 = 15
after 2nd loot, no. of breads left = (15+0.5)x2 = 31
after 1st loot, no. of breads left = (31+0.5)x2 = 63
So, before 1st loot, no. of breads left = (63+0.5)x2 = 127

Answer / guest
127 is the correct answer.
When the last thief comes the number of bread will be 7.
Later on going upwards it takes the formula
2x+1 ie 2*7+1 =15 no will be there when Fourth thief comes
and so on.
for third thief 2*15+1 ie 31 bread will be there
for second thief 2*31+1 ie 63 bread will be there
for first thief 2*63+1 ie 127 bread will be there

3---> 3*2+0.5=6.5 ----> 6.5*2+0.5=13.5 ---
---> 13.5*2 + 0.5=27.5 ----> 27.5*2+0.5=55.5----
---> 55.5*2=111

Answer / chandra prakash garg
I think initialially total bread were 225.
How:
Let it be x.
(x+1)/2 + (x+3)/4 + (x+7)/8 + (x+15)/16 + (x+31)/32 + 3 = x.
Solve the equation, you will get the answer.

Answer / niraj
remaining bread= 3
5th thief loot 1/2totatl no of breads & 1/2 of bread
means breads were 3+3+1/2=6&1/2
similarly
4th thief loot 6.5+6.5+.5=13.5
3rd 13.5+13.5+.5=27.5
2nd 27.5+27.5+.5=55.5
so at the time of 1st thief
no. of breads were 55.5+55.5+.5= 111.5
