Answer

Let no of breads initially are x.
Then,
x-(x/2 + x/4 + x/8 + x/16) = 3
x- 15x/16 =3
x/16 =3
x=48

Answer
# 4
Mr.Ramki,
Assume,total no of breads,x=48
first person stole,x/2 = 48/2 = 24.
second person stole,x/4 =(x/2)/2 = 24/12 =12.
third person stole, x/8 = (x/4)/2 = 12/2 =6.
fourth person stole, x/16 = (x/8)/2 = 6/2 =3.
Total breads stolen= 24+12+6+3 =45.
Still at the end there are 3 breads remaining what has
mentioned in the given question.
Hence no of breads initially are,48.

If we assume no of breads initially,x=63.
first person=31
second person=15
third person=7
fourth person=3
Breads stolen=31+15+7+3=56
Remaining breads=63-56=7
But in the question at the end there must be 3 breads
remaining,but in your logic 7 breads remaining,so 63 is
wrong one.

Answer
# 8
soln:
no of breads initially=x
breads taken by first thief= x/2+1/2=(x+1)/2
remaining breads= x-((x+1)/2)=(x-1)/2
breads taken by second theif= ((x-1)/4)+1/2=(x+1)/4
remaining breads= x-((x+1)/4)=(x-1)/4
similarly,
remaining bread after third theif rob=(x-1)/8
remaining bread after forth theif rob=(x-1)/16
therefore,
(x-1)/16=3
x-1=48
x=49
