Lừa và ngựa thồ hàng ra chợ,
Ngựa thở than mình chở quá nhiều.
Lừa rằng:"Anh chớ lắm điều!
Tôi đây mới bị chất nhiều làm sao!
Anh đưa tôi một bao mang bớt
Thì tôi thồ nhiều gấp đôi anh
Chính tôi phải trút cho anh
Một bao gánh đỡ mới thành bằng nhau!"
Hỏi lừa,ngựa chở mấy bao?
Giải
Nếu lừa chuyển cho lừa một bao thì lừa và ngựa chở bằng nhau, vậy lừa chở nhiều hơn ngựa :
1 + 1 = 2(bao)
Nếu lừa chuyển cho lừa một bao thì lừa sẽ chở hơn ngựa 2 bao nữa , khi đó lừa nhiều hơn ngựa:
2 + 2 =4(bao)
Khi đó ngựa chở : 4 bao
lừa chở : 4 x 2 = 8 bao
Ban đầu ngựa chở : 4 + 1 = 5(bao)
Ban đầu lừa chở : 8 - 1 = 7(bao)
Đáp số: Lừa: 7 bao
Ngựa: 5 bao

The Penny Black
It might not have looked very impressive, but the Penny Black, now 170 years old, was the first stamp to be created and it launched the modem postal system in Britain.
Before 1840 and the arrival of the Penny Black, you had to be rich and patient to use the Royal Mail. Delivery was charged according to the miles travelled and the number of sheets of paper used; a 2-page letter sent from Edinburgh to London, for example, would have cost 2 shillings, or more than £7 in today’s money. And when the top-hatted letter carrier came to deliver it, it was the recipient who had to pay for the postage. Letter writers employed various ruses to reduce the cost, doing everything possible to cram more words onto a page. Nobody bothered with heavy envelopes; instead, letters would be folded and sealed with wax. You then had to find a post office - there were no pillar boxes - and hope your addressee didn't live in one of the several rural areas which were not served by the system. If you were lucky, your letter would arrive (it could take days) without being read or censored.
The state of mail had been causing concern throughout the 1830s, but it was Rowland Hill, an inventor, teacher and social reformer from Kidderminster, who proposed a workable plan for change. Worried that a dysfunctional, costly service would stifle communication just as Britain was in the swing of its second industrial revolution, he believed reform would ease the distribution of ideas and stimulate trade and business, delivering the same promise as the new railways.
Hill’s proposal for the penny post, which meant any letter weighing less than half an ounce (14 grams) could be sent anywhere in Britain for about 30p in today’s money, was so radical that the Postmaster General, Lord Lichfield, said, 'Of all the wild and visionary schemes which I ever heard of, it is the most extravagant.’ Lord Lichfield spoke for an establishment not convinced of the need for poor people to post anything. But merchants and reformers backed Hill. Soon the government told him to make his scheme work. And that meant inventing a new type of currency.
Hill quickly settled on 'a bit of paper covered at the back with a glutinous wash which the user might, by applying a little moisture, attach to the back of a letter’. Stamps would be printed in sheets of 240 that could be cut using scissors or a knife. Perforations would not arrive until 1854. The idea stuck, and in August 1839 the Treasury launched a design competition open to ‘all artists, men of science and the public in general’. The new stamp would need to be resistant to forgery, and so it was a submission by one Mr Cheverton that Hill used as the basis for one of the most striking designs in history. Cheverton, who worked as a sculptor and an engineer, determined that a portrait of Queen Victoria, engraved for a commemorative coin when she was a 15-year-old princess, was detailed enough to make copying difficult, and recognisable enough to make fakes easy to spot. The words ‘Postage’ and ‘One Penny’ were added alongside flourishes and ornamental stars. Nobody thought to add the word ‘Britain’, as it was assumed that the stamps would solely be put to domestic use.
With the introduction of the new postal system, the Penny Black was an instant hit, and printers struggled to meet demand. By the end of 1840, more than 160 million letters had been sent - more than double the previous year. It created more work for the post office, whose reform continued with the introduction of red letter boxes, new branches and more frequent deliveries, even to the remotest address, but its lasting impact on society was more remarkable.
Hill and his supporters rightly predicted that cheaper post would improve the ‘diffusion of knowledge’. Suddenly, someone in Scotland could be reached by someone in London within a day or two. And as literacy improved, sections of society that had been disenfranchised found a voice.
Tristram Hunt, an historian, values the ‘flourishing of correspondence’ that followed the arrival of stamps. ‘While I was writing my biography of Friedrich Engels I could read the letters he and Marx sent between Manchester and London,’ he says. ‘They wrote to each other three times a day, pinging ideas back and forth so that you can almost follow a real-time correspondence.’
The penny post also changed the nature of the letter. Weight-saving tricks such as cross-writing began to die out, while the arrival of envelopes built confidence among correspondents that mail would not be stolen or read. And so people wrote more private things - politically or commercially sensitive information or love letters. ‘In the early days of the penny post, there was still concern about theft,’ Hunt says. ‘Engels would still send Marx money by ripping up five-pound notes and sending the pieces in different letters.’ But the probity of the postal system became a great thing and it came to be expected that your mail would not be tampered with.
For all its brilliance, the Penny Black was technically a failure. At first, post offices used red ink to cancel stamps so that they could not be used again. But the ink could be removed. When in 1842, it was determined that black ink would be more robust, the colour of the Penny Black became a sort of browny red, but Hill’s brainchild had made its mark.
