Solve this one as well.....


1) A woman went into a bank to cash an insurance refund check. By mistake the teller gave her dollars for cents and cents for dollars. She put the money in the purse but accidentally dropped a nickel on the floor. When she got home, she found that she had exactly twice the amount of the check she had cashed. She didn't have any money in her wallet before going to the bank. What was the exact amount of that check??


2) A logician with some time to kill in a small town decided t get a haricut. The town had only two barbers, each with his own shop. The logician glanced into one shop and saw that it was extremely untidy. The barber needed a shave, his clothes were unkempt, his hair was bad. The other shop was extremely neat. The barber was freslhyl spotlessly dressed, well shaved with a trimmed hair. 

Why did the logician return to the first shop for his haircut?
