I once cashed a cheque at the bank. I had spent £5.67 before I realised the bank clerk had made a mistake. He had transposed the pounds with the pence. I now had exactly 4 times the value of the original cheque. What was the original cheque's value?

Exactly how many minutes is it before six o'clock if 50 minutes ago it was four times as many minutes past three o'clock?

Which four letter word can be placed between the two following words to make two new ones:

ARM[...]ING

Which letters come next in this sequence:

TO NE US RN ER RS ==?==

You have the misfortune to own an unreliable clock. This one loses exactly 13 minutes every hour. It is now showing 11:45am and you know that is was correct at midnight, when you set it. The clock stopped two hours ago, what is the correct time now?
