9 hours because 8 x 3 = 24 and 3 x 3 = 9
With the 3 colors - red=1, yellow=2 and green=5 - adding up to 8, that is one quarter the total of 32. Multiply each by 4 and you'll have - 4:8:20.
Solution-
First 9 letters of alphabet are- A,B,C,D,E,F,G,H,I
Total number of ways of selection of 4 letters from 9 alphabets = 9C4
=9!÷((4!).(9-4)!) = 9!÷(4!×5!) = (9×8×7×6)÷(24) = 126
The number of ways of arranging these 4 numbers = 4! = 24
∴ Total number of possible permutations = 9C4×4! = 126×24 = 3024
∴ option number 2 is correct.
To rotate a point around the origin by 180 degrees, multiply both parts of the coordinate point by 
. (This means you go from 
to 
.)
0.6cm or 6mm if you take 5*12% you can get the answer pretty easy :)
