You have a rock solid dark chocolate bar of size 2 x 8. You need to break it and get 1 x 1 pieces of that chocolate.
If you can break that bar only along its length or breadth, how many times will you have to break to get the 1 x 1 pieces?	Choose the correct choice from the following
A) 12 times.
B) 13 times.
C) 14 times.
D) 15 times.
E) 16 times.
Solution:   There is a simple logic to solve this question.   The size of the chocolate is 2 x 8. Thus, you need to have 2 x 8 = 16 pieces.   Every time you break the chocolate, you will get one extra piece.   Thus, to get 16 pieces, you must break it  (16 - 1)=
