half of bread and half of loaf of a bread
for four half no. of subsequent bread and half loaf is
(x2 +1/2) +(x4 +1/2) + (x8+1/2) + (x16 +1/2) + 3=x
15x/16 +5=x
x/16=5
x=80
its the answer

Let total number of breads available is x.
Then x/2+x/4+x/8+x/16+3=x
By solving this we can get x=48.

let the total no of breads are X
now,each one took half of bread and half a loaf so
1st one=X/2
2nd one took half i.e from rest means= X/4
similarly 3rd = X/8
4th=X/16
and all took half a loaf i.e =1/2*4
and in question they mentioned 3 breads are remains
total (X)=(X/2+X/4+X/8+X/16)+1/2*4+3
X=15/16x+2+3
X/16=5
so x= 16*5
=80

Let total number of breads available is x.
Then x/2+x/4+x/8+x/16+2(=4*1/2 since each person take half of a loaf)+3=x
By solving this we can get x=80.

it will be 63
procedure:
let initially der are x breads
1st thief takes=x/2 +1/2 ,so remaining=x-(x/2+1/2)=x/2-1/2
2nd thief takes=1/2+1/2*(x/2-1/2)=1/2+x/4-1/4=x/4+1/4 so remain=x/2-1/2-x/4-1/4=x/4-3/4
3rd thief takes=1/2 +1/2*(x/4-3/4)=1/2+x/8-3/8=x/8+1/8 so remain=x/4-3/4-x/8-1/8=x/8-7/8
4th thief takes=1/2+1/2*(x/8-7/8)=1/2+x/16-7/16=x/16+1/16 so remain=x/8-7/8-x/16-1/16=x/16-15/16
so x/16-15/16=3
x=48+15=63(ans)
