#384. 'How quickly can you find out what is so unusual about this paragraph? It looks so ordinary that you would think that nothing is wrong with it at all, and, in fact, nothing is. But it is unusual. Why? If you study it and think about it, you may find out, but I am not going to assist you in anyway. You must do it

without coaching. No doubt, if you work at it for long, it will dawn on you. Who Knows? Go to work and try your skill. Par is about half an hour.' Quimby Sereye, the editor of a local magazine, is at his wit's end. The above puzzle was submitted without an answer, and Quimby's been trying to solve it for over a week. Day and night, wherever he goes, Quimby's been studying it without success. Can you solve this perplexing problem and bring tranquility back into Quimby's life?

Hi bobbym,

The solution #384 is correct! Stupendous!

#385. Trusting Ned Armstrong, the owner of Ned's Wonderful World of Sports, made his first sale the other day to a somewhat suspicious looking gentleman. The customer purchased a package of golf balls for $12 and paid Ned with a $20 bill. Ned was all out of singles so he went next door to the bakery to change it; then he gave the customer his purchase and $8 in change. Ten minutes later the baker came in complaining that Ned had given him a counterfeit bill. Ned took back the bogus twenty and gave the baker a $20 bill from the register. Now, the big question in Ned's mind was just how much money had he lost on his first sale? Keep in mind that the marup on a package of golf balls is 100 percent.
