Solution for 5th:
for 2X2 the number for clickks requried is 2.
Example: B | w
-----
W | B
click on the B
-
W
then
W | w
-----
B | B
click on line B|B
then
w | w
-----
W | w
So for 2x2, we nee 2( 2^1) clicks
for 3x3, we need 4( 2^2) clicks
for 4x4, we need 8 ( 2^3) clicks
Generally, for nxn, we need ( 2^(n-1) ) Clicks
so
for 96*96 , we need 2^97 clicks.

FOR THIS ISSUE I AM GOING TO REVEAL THE ANSWER FOR 5 TH QUESTION, HERE IS THE ANSWER FOR THAT
When alternate columns are selected and switched colours, we get each row of same color, with alternate rows of different colors. Thus we need 49 clicks to get this result. Next 49 clicks on alternate rows will get us chess board of same color, hence 98.

Dear Bharath,
As per mentioned in the question.
We have to consider the Individual blocks and we need to switch the color of each block.
But as per your explination , you are considering the entire row,and it is switching.
Is it agreeable?
No,I dont think so.
