Solution to Covent Garden Problem
The mixed apples were sold of at the rate of five apples for two pence. So they must would have had a multiple of five i.e. 5, 10, 15, 20, 25, 30,…, 60, 65,… etc apples.
But the minimum number of apples they could have together is 60; so that 30 would have been of Mrs. Smith's that would fetch her 10 (an integer) pence and the other 30 of Mrs. Jones's that would fetch her 15 (also an integer) pence.
When sold separately it would fetch them 10+15=25 pence altogether. But when sold together it would fetch them 60X2/5=24 pence i.e. a loss of one (25-24=1) pence.
Since they lost 7 pence altogether; they had altogether 60X7=420 apples that fetched them only 420X2/5=168 pence and they shared 84 pence each of them. But Mrs. Jones could sell her 420/2=210 apples for 210/2=105 pence so she lost "21 pence".

Covent Garden Problem
Here is a puzzle known as the Covent Garden Problem, which appeared in London half a century ago, accompanied by the somewhat surprising assertion that it had mystified the best mathematicians of England:
Mrs. Smith and Mrs. Jones had equal number of apples but Mrs. Jones had larger fruits and was selling hers at the rate of two for a penny, while Mrs. Smith sold three of hers for a penny.
Mrs. Smith was for some reason called away and asked Mrs. Jones to dispose of her stock. Upon accepting the responsibility of disposing her friend's stock, Mrs. Jones mixed them together and sold them of at the rate of five apples for two pence.
When Mrs. Smith returned the next day the apples had all been disposed of, but when they came to divide the proceeds they found that they were just seven pence short, and it is this shortage in the apple or financial market which has disturbed the mathematical equilibrium for such a long period.
Supposing that they divided the money equally, each taking one-half, the problem is to tell just how much money Mrs. Jones lost by the unfortunate partnership?
Chapter 4 – Simultaneous Equations
In this chapter, students will be taught to solve simultaneous equations using the substitution method and solve simultaneous equation involving real-life situations.
1. Solve simultaneous equations in two unknown: one linear equation and one non-linear equation.
1.1 Solve simultaneous equations using the substitution method
The following simultaneous equation consists of a linear equation and a non-linear equation (up to second degree only).
Solving the equations means finding 2 sets of solutions that satisfy both the equation given, a linear equation and a non-linear equation. A general method of solution is to make one of the unknowns the subject of the linear equation, then substitute this value in the non-linear equation.From (i) we obtain y = 2x – 3 (iii)
Substitute y= 2x - 3 into (ii)

- Tips For Exam
Ten Tips - Exam techniquesTests and exams are a regular part of the school
environment. It is important that exams be kept in proportion - they are
important, but not the end of the world. Some things can be done to make exams a
more valuable, worthwhile and less threatening experience for students.
all necessary material with youYou can't borrow items such as pens, pencils,
rulers or special equipment while in anexamination.
2. Have a relaxing night
before your examsHave an early night, and try to have a healthy breakfast
Read the entire paper.Where you have choices, decide which ones you plan to
4. Plan your time.Spend some time drafting a plan for the questions you
choose to answer.
5. Jot down ideas as they come to you.While you are answering
one question, information about another may suddenly occur to you. Jot it down
somewhere because when you come to that question perhaps an hour later,you may
have forgotten it.
6. Don't leave any questions unanswered.If you are short of
time, use note form. Remember, you can only be marked on the answers you give.
Never leave the room early.If you have time at the end, go over your work, add
information (eg in the margin). You can'treturn if you suddenly remember a fact
after you have left.
8. Do not spend too long on multiple choice questions.With
multiple choice questions it is best to cover the answers and work out your own
beforelooking at the choices on paper. If you can't answer the question come
back to it later - have aguess.
9. Never omit an entire question.No matter how
well you answer other questions, you must leave time for all questions -
aperfect answer can still only earn a certain number of marks. If you write
nothing, you can'treceive any marks and you have lost all your marks for a
particular question. Write something - it may at least give you a few points.
Maintain a stable energy level.Eating foods such as chocolate bars before an
exam might give you an energy boost to beginwith but your blood sugar levels
will drop within an hour and your energy will plungedramatically, making it hard
for you to concentrate

Tawau dan Pulau Mabul, Sabah. 7-10/5/2009
Percutian nie.. actually aku nak bagi can anak naik kapal terbang merentas udara
Alhamdulillah dpt cuti dan berjaya menjoinkan diri ke Mabul… Yatta! \(^_^)/.. dan beginilah percutian kami bermula…
Tidur di hotel dekat dengan Masjid Lama tawau supaya senang untuk solat.
Antara lokasi cantik untuk scuba adalah di Lobster wall, Paradise, Froggy Lair, Coral Heaven and many others.. Selain tue, kedudukan pulau nie yg juga berhampiran dgn negara jiran seperti Indonesia dan Filipina membuatkan majority org-org kat sinie adalah dr bangsa mereka dan bajau laut (sea gipsies).
sbb tue dier lebih muslimah (^^’)
dan lagi satu diorng nie dah tahap professional dah kalo bab² jadi model untuk kita amik gambar.. (^^,) sbb dah biasa sgt..
Erm.. actually kalau nak ke Kapalai, Pulau Sipadan atau ke mana² selain drpd yang telah dilistkan dlm pakej tue mmg boleh; tapi perlu top-up harga lain lah.. so lepas berpakat².. maka kami pun top-up sorang RM50++ untuk bersnorkeling di area Kapalai..
Asalanya terdapat daratan-pulau di sini, tapi berikutan hakisan pasir pantai oleh ombak dan peningkatan aras laut yang semakin ketara, aras ketinggian pulau ini semakin lama dilihat semakin merosot
Deng!.. tempat nie mmg cantik!.. Serious cantik.. lebih cantik dr dua tempat snorkelling kami sebelum nie..
then tadi ada a school of fish buat kawat renang laks depan aku.. ke hulu- kehilir.. hehe sgt cantik… dan ada tapak seleman kaler biru.. kalau tgk lelama mcm jejari puak Na’vi (Avatar).. (^^’)
Dan setibanya di sana.. kami di bawa ke pasar pagi Semporna.. terus ke kawasan org jual ikan kering dan ikan masin..
Oh!.. dan mujurlah kami tak borong hasil² laut nie dr awal.. kalau tak habis busuk beg ngan bau ikan masin/kering.. Ini pun dah busuk dah.. huhuu(^o^)..
Tapi apa-apa pun.. percutian kali nie sangat berbaloi.. juga hadiah harijadi paling best (^_^).. sbb; akhirnya berjaya menjejakkan kaki di semua negeri di Malaysia. Lepas nie boleh istihar: “Dah Jalan 1 Malaysia”.. hahahaaa.. Saiko naaa~
“Empat belas melintang jalurnya… semua negeri dalam melesiaaa.. ”
