# Who was the murderer? 550971051

The florist has just been murdered, and you, a freelance detective called on to the case by the police, arrive at the crime scene. Three suspects are present in the flower shop: the florist's assistant, the boss of the oil shop next door, and a person who was caught running away from the crime scene shortly after the victim's scream was heard.

On the floor is a blood-stricken ripped piece of paper with the numbers 550971051 in the florist's handwriting.

Who was the murderer?

The boss of the oil shop next door.

Why?

550971051 flipped upside down and reversed looks like ISOILGOSS $\rightarrow$ I sell gas

I've heard this puzzle somwhere before, can't remember where, I'm quite sure this is the answer though

• Your answer and method is correct, but 550971051 upside-down being interpreted as 'I sell gas' is a bit vague. Anyways, I'm going to mark your answer as correct because you have both the answer and the process right

• Thanks! I think I heard this riddle with the murderer being a gas seller instead of oil boss (both meaning similar), so I just wrote what I remember, not realizing that ISOIL6OSS can have 6 $\rightarrow$ b instead of G Jul 21 '17 at 4:43

Should be

the oil guy

because

550971051 inverted is IS OIL BOSS (15 01L b055)

• Good job on the answer, but the correct way is to read the number upside down. You can try that, I guess :)

• But the answer is derived from reading the number upside down already. Jul 21 '17 at 4:52
• This should be the correct answer. The world is unfair sometimes. @Non-Puzzler Jul 21 '17 at 14:14
