Part 10

273. If eight men are engaged in a tug-o’-war, four pulling against four, on a continuous rope, and each man is exerting a force of 100 lbs., what strain is there at the centre of the rope?

“FIND OUT.”

274. A gentleman in a train with a boy got into conversation with a stranger, who asked him the lad’s age. The boy quickly replied, “This gentleman, who is my uncle, is twice as old as me, but the sum of the figures in my age are twice the sum of those in his.” What was the age of each?

275. One of our squatters who had made his fortune in the “good times” determined to sell his run and spend the rest of his days in the old country. A new chum, possessing considerable wealth, and desirous of settling down in Australia, hearing of the squatter’s intention, interviewed him with the object of purchasing, when the following conversation ensued:--

NEW CHUM: “How big is your run? What’s its area?”

SQUATTER: “Well, I’m blessed if I know, but I can tell you it’s perfectly square and enclosed with posts and rails. Each of the rails is 9 ft. long.”

NEW CHUM: “Oh, then, is it what you call a three-railed paddock?”

SQUATTER: “Yes, that’s so, and now I remember that _the number of rails in my run is equal to the number of acres_. If you like you can take a horse and ride round and count the rails, then you will know the area.” This advice the new chum acted upon.

Find out the length of his ride and the area of the run.

A Federal Problem.

It is well known to our readers that paper money--such as pound notes--issued in one colony are depreciated in another; thus a one pound note of N.S.W. is only worth 19s. 6d. in Victoria, and _vice versa_. Some time ago a rather ’cute individual in Wodonga, on the Victorian side of the border, bought a drink in a local hotel with a Victorian note, and received in change a N.S.W. note, which was worth then and there only 19s. 6d.; he thereupon crossed the Murray to Albury on the New South Wales side, bought another drink for sixpence with his N.S.W. note, and received a Victorian note equal to 19s. 6d. in change. He travelled backwards and forwards during the day, getting his twentieth and last drink in Albury, on the N.S.W. side, whereupon he returns to Wodonga with a Victorian pound note still to his credit. He thus paid for all his drinks, which amounted to ten shillings. Who lost the money?

We cannot advise readers to “go thou and do likewise,” for the simple reason that such a proceeding would now be impossible, as exchange is no longer charged in the two towns mentioned. It is not until we get further from the border that the levy is made.

Doing Two Things at Once.

An inspector was examining a school in a country district some distance from a railway station. He was afraid of losing his train, so hurrying with his work he tried to do two things at once. Standing in the doorway, he gave out dictation to Class III. in the main room, and at the same time gave out a sum to Class IV. in an adjoining room, jerking out a few words alternately.

The sum was “If a couple of fat ducks cost 19s., how many can he get for £72 10s. 9d.” The dictation for Class III. began “Now as a lion prowling about in search, &c.” Of course the poor children heard both, and got a bit mixed. One little girl’s dictation began “Now a couple of ducks prowling about in search of a lion who had lost 19s., &c.” While a Class IV. lad was scratching his head over the following sum “If 72 couples of fat lions cost 19s., how much prowling could be got for £72 10s. 9d.”

TWO CALENDAR CATCHES.

Ask a person if Christmas Day and New Year’s Day come in the same year. The answer generally given is “Of course not, Christmas comes in this year, and New Year’s Day in the next.”

Another question that often puzzles many. Have we had more Christmas days than Good Fridays? The usual answer is “No, both the same.”

276. A brass memorial tablet in honour of the late Sir Charles Lilley has been fixed in the centre of the eastern wall of the Brisbane Grammar School Hall. The enthusiasm displayed by Sir Charles in the cause of education generally, and his work on behalf of the Grammar School, make this commemoration particularly appropriate. The following is the inscription, to translate which should prove a capital exercise to all Latin scholars. The tablet measures 50 inches by 30 inches.

[Illustration: MEMORIAL TABLET TO THE LATE SIR CHARLES LILLEY]

It may be added that the lettering of the plate was designed by Mr. R. S. Dods, architect, and the engraving was done in Brisbane by Messrs. Randle Bros., the well-known engravers, of Elizabeth Street.

A Puzzle in Book-keeping.

277. A firm appointed an agent to do business on their account, and gave him £32 17s. in cash for expenses, &c., and also supplied him with a stock of goods, the value wholesale being £57 14s.; while in a distant town he bought a job lot of goods for £59 19s., which he paid cash for out of what he had realised on his first stock. He still continued to sell, but very soon after the firm called him in, and desired him to close his account and hand in a full statement.

His total retail sales amounted to £102 17s., and he returned goods to the value of £31 17s., his expenses had been £25.

Question--What does the firm owe the agent, or the agent owe the firm?

THE AGENT’S STATEMENT BEING--

Cash £32 17 Goods 57 14 Paid for Goods 59 19 Cash Sales 102 17 Goods Returned 31 17 Expenses 25 0

This puzzle first appeared in “HOW TO BECOME QUICK AT FIGURES,” the answer being withheld. It is a record of transactions that actually occurred in America, which were the subject of litigation. Although we received thousands of replies, not more than 5 per cent. were correct. It is a question that individuals not conversant with book-keeping would be as likely to solve correctly as the expert. For the convenience of those who are unacquainted with American money we have been obliged to substitute £ s. d., and would advise our readers to attempt a solution before referring to the answer.

My friends,--I have spare blankets, and I shall need no more; The tenth man can have my bed, and I’ll sleep on the floor. In room marked A two men were placed; the third was lodged in B; The fourth to C was then assigned, the fifth retired to D; In E the sixth he tucked away, in F the seventh man, The eighth and ninth in G and H, and then to A he ran (Wherein the host, as I have said, had laid two travellers by); Then taking one--the tenth and last--he lodged him safe in I: Nine spare rooms--a room for each--were made to serve for ten. And this it is that puzzles me and many wiser men.

(53) The versed sine of the segment of Will’s cake which was given to Jack was 3·05 inches, and its area 26·0058364375 square inches: hence Will’s share was 704·6125135625 square inches, and Jack’s share 704·5914364375 square inches; so that Will’s four were about 52·03275 square inches more than Jack’s six, and Will, of course, lost the wager. After the decision of the gauger, Will’s share was ·0210771245 (1-50th nearly) of a square inch more than Jack’s.

(93) The difficulty is to determine what would have been the will of the testator had he foreseen that his wife would be delivered of twins. As he desired that in case his wife brought forth a son he should have ⅔ of his property, and the mother ⅓, it follows that his intention was to give his son a sum double to that of the mother; and as he desired in the other case that if she brought forth a daughter the mother should have ⅔ and the daughter ⅓, there is reason to conclude that he intended the share of the mother to be double that of the daughter; consequently, to unite these two conditions, the heritage must be divided in such a manner that the son may have twice as much as the mother, and the mother twice as much as the daughter. Thus we get--

Son’s share, £4000 Mother’s " £2000 Daughter’s " £1000

Sometimes the following difficulty is proposed in regard to this problem:--In case the mother should have two sons and one daughter, in what manner must the property be divided then? We refer you to the lawyers.

To explain this often causes much confusion. We must take a simple illustration: I have a garden containing 10 appletrees, all bearing fruit. Now, there are more trees than any tree has apples on it; there must be at least 2 trees having the same number of apples--for instance, if No. 1 tree has 1 apple, No. 2 has 2, and so on to No. 9; when we come to No. 10 tree, it must have the same as one of the other trees, as it could not have 10 or more according to our first supposition.

This is one of those _impossible_ questions that one often hears. The fractions, when added together, equal 19/20. So the whole £1 _cannot be so divided_. The following solution is often put forward:--
