How on earth did you get to that figure. My initial thought was £170, but then I realised that was just too obvious.
You are All wrong, the thief wouldn't come back to that store again so the answer is still £100 short (c)

Read the post properly Mike, most of us got the £100 and we've been explaining why; and the thief would definitely have gone back for a second go, as most get off with just a warning, he just wouldn't have paid for anything on the second visit.
Actually the question doesn't ring true.
Had the thief stolen £100.00 in £10.00 notes, then he would only have offered £70.00 in payment, no change would then need to be offered.
To get £30.00 change he would have had to have stolen a £100.00 note, and offered that for payment, raising suspicion with the shopkeeper.

Of course O did read it but I also wanted to add a little spice to the quiz, but actually I will be honest, I had to work it out!
e.g.

Newboy
Or two £50 notes

It's not meant to, it's just designed to see if you get caught out by the obvious traps.
I think you could argue that the thief returning isn't immaterial, it's one of the events which we're being asked to mathematically take into account - in which case
there's not enough info in the question to give a definitive answer. The effect of the purchase on how out of pocket the shopkeeper is, is unknown.
Scenario A:
£100 stolen
therefore £100 out of pocket
£70 returned, therefore out of pocket by £30...
for goods which cost (out of pocket) nothing (fell off the back of a lorry)
therefore out of pocket by £30
Scenario B:
£100 stolen
therefore £100 out of pocket
£70 returned, therefore out of pocket by £30...
for goods which cost (out of pocket) £80 (it's a loss-leader to encourage new trade)
Therefore out of pocket by £30 plus £80, total £110
Scenario C:
The shopkeeper had a £500 bet with a friend that he could sell the goods, which were given to the shopkeeper for free. No-one was ever going to buy them, because they were useless. The thief (for whatever reason) bought them
Therefore out of pocket by £30, but up by £500, so a £430 profit overall.
You can't know how much the shopkeeper is out of pocket by these events unless you know the effect on his or her pocket of the sale.

I agree so the answer is not £100, but £130, because no change was given, and £100 notes don't exist
I think there has to be a scenario D, how would the shopkeeper know how much money he had lost since if he didn't know what was inside his old fashioned register that didn't have a tally counter?
so really the shopkeeper would think customer spending who spent £70 was a real good gem, and he would have been happy to have a sales figure of £170 for the day.
Nonsense.
A person went into a shop and bought something for £70, gave shopkeeper £100 and received £30 change.
He went back later and stole £100. How much is the shopkeeper out of pocket?

£170, because he can't be a good and Professional thief (Registered with Tills Safe body) if he doesn't empty the entire till. If he left any money behind, he didn't do his job right.
