- Sorry I did mistake.
Ans is 2*2*2*2*2*1*1*1*1 =32 - 8 years agoHelpfull: Yes(7) No(3)
- 3*3 matrix = 9 therefore, 9c2 ways = 36 ways
- 8 years agoHelpfull: Yes(5) No(4)
- this matrix follows 2*2*2*2*2*1*1*1*1 finally we get 32as answer
- 8 years agoHelpfull: Yes(5) No(1)
- for 3*3 matrix if we rotate 180 degrees , there are 32 ways
- 8 years agoHelpfull: Yes(3) No(7)
- Ans: 35
The matrix can be filled by following ways
2 2 2
2 2 1
1 1 1
So 2*2*2*2*2*1*1*1*1= 35
