The victim has been stubbed on his right side. But when  you come in front its your left side. The person  paying cash is using his right hand, however the other one is using his left hand to look at the green jacket. so he is the murderer

The black colors forms the word Good and the white color forms the word Evil

We can do it  like this

At morning when people go to work they want to go down. If she lives on floor  9 then all the people above her (27 floors)  are likely to get down so than why whichever one she takes is three times more likely to be going up than down.

This tradition stems from the era of dressing where women were dressed by maids or servants and it was easier to dress them if the buttons were on the left side. On the other hand, men dressed themselves and it was easier if the buttons were on the right side. This distinction has continued till today and is largely considered a gender-based convention.

Solution: We have been told that D=5
D+D = T  >> 5+5 = 0 (1) so  T = 0 since L+L gives us an even result and we add 1 from the sum of T+T so R must be an odd number.
Now, D+G < 10 >> 5+G < 10 =R so R can be 7 or 9, but since O+E =O than means that E is 9 so R can only be 7 and since O+E > 10 than means that G must be 1.
We see that A+A = E, but since A+A will result an even number but the sum is an odd number (E=9) than L+L must create a carry. So  L+L+1 = R=7 that L is not 3 but L=8 and A is oncourse 4

so the final is:
5 2 6 4 8 5
+ 1 9 7 4 8 5
==========
7 2 3 9 7 0

(0!+0!+0! )!= 6
(1!+1!+1!)! = 6
2 + 2 + 2 = 6
3 *3 -3 =  6
sqrt(4) + sqrt(4) + sqrt(4) = 6
5 + 5/5 = 6
7 – 7/7 = 6
8 – sqrt(sqrt(8+8)) = 6
sqrt(9 * 9) – sqrt(9) = 6
