A customer at a 7-11 store selected four items to buy, and was told that the cost was 7.11. He was curious that the cost was the same as the store name, so he enquired as to how the figure was derived. The clerk said that he had simply multiplied the prices of the four individual items. The customer protested that the four prices should have been ADDED, not MULTIPLIED. The clerk said that that was OK with him, but, the result was still the same: exactly 7.11. What were the four prices?

I recently gave a new watch to my friend for their birthday.
However, as usual with my presents, it was quite useless as it gains 6 minutes every hour.
I set it using my own accurate clock at midnight and the watch now shows 8.26am.
I know that it stopped 30 minutes ago, so what is the correct time now?
Hint: How many watch minutes will pass in a real hour?
Since the watch is gaining 6 minutes every hour, for every real hour that has passed, the watch will only show 66 minutes. Since the watch shows 8.26am, we know that 506 watch minutes have passed. This therefore equals 460 real minutes and hence 7 hours and 40 minutes. The watch stopped 30 minutes ago, therefore the time must now be 8.10am.
