In a 3*3 square grid comprising 9 tiles each tile can be painted in red or blue color. When the tile is rotated by 180 degree, there is no difference which can be spotted. How many such possibilities are there?
a) 16 b)32 c)64 d)256
Read Solution (Total 11)
-
- ans is 32 .
ans grid has to be rotated at 180 degrees.
hence,
11=33
12=32
13=31
21=23
22=22
31=13
32=12
33=11
cell 11-33 can be altered in 2 ways (as thr are 2 colours)
cell 12-32 can be altered in 2 ways
cell 13-31 can be altered in 2 ways
cell 21-23 can be altered in 2 ways
and , cell 22 can be altered in 2 ways
, so
2X2X2X2X2 = 32.

- if u are rotate 180degree in 5 possible place in 2 colors
consider3*3grid
b d c
e a e
c d b
so a,b,c,d,e are colored red or blue
a rotate 180degree and possilble there is no difference which can be spotted
similarily to b,c,d,e.

- 5 possibilties so 2^5=32

- This grid even rotated 180 degrees the relative positions of the tiles do not change. So we paint tile number 1's with red or blue (only one color should be used) , 2's with red or blue.....tile 5 red or blue. Then total possibilities are 25 = 32

- Ans: B
This grid even rotated 180 degrees the relative positions of the tiles do not change. So we paint tile number 1's with red or blue (only one color should be used) , 2's with red or blue.....tile 5 red or blue. Then total possibilities are
