Number the packs one through ten. Take 1 cig from pack #1, two from 2, etc. The amount of grams (or, in this case, I guess tenths of a gram) that the total is short of the expected weight, is the number of the pack that's light.

put them all on the scale & take 1 off at a time to see which 1 weighs differently cause you will still have all the others on the scale until it has a different weight & then thats the 1 thats different

The answer seems obvious if you have a scale weigh the one that seems to be lighter than the others. Or its the brand that is unlike the other 9.

could you just pick them all up one by one and see which one felt lightest before ever putting it on a scale? you wouldn't use your one guess using the scale until you had guessed which was the fake using your hands.

I'll put nine packs on the scale.
One pack at a time.

Both are real. Just that 9 grams are called "Lights".
