Error in text book?

[Jennylim]

I was reading Form 1 Kemahiran Hidup text book written by Zulkifli , Zainal and Tuslah, at page 352, section 3.3.3 and 3.3.4 seems to give contradicting explanation.

On page 368, question no 9, I can not find a logical way to calculate the cost of production per unit base on the theory given by the text book.

The book is the 11 release and was printed in 2006. So, it is unlikely that the book can be wrong, but I can not find any logical answer that they are indeed correct.

Anyone read that part of the book? or care to have a look to see if you can find a logical explanation?

Kos bahan mentah : Kayu RM5.00, Paku RM0.20, Syelek RM0.50
Jumlah :RM5.70

Jadual di atas menunjukkan kos bahan mentah untuk menghasilkan seunit rak kasut. Kos sampingan untuk menghasilkan 10 unit rak kasut ialah RM2.00 dan kos upah bagi menghasilkan 10 unit ialah RM10.00.

Berapakah kos pengeluaran seunit rak kasut?

In the earlier pages, the book says:
Kos pengeluaran=kos bahan mentah+kos upah + kos overhed

Kos pengeluaran seunit = kos pengeluaran/kuantiti yang dihasilkan

RM6.90

hi jenny,

i think maybe not an error, obviously he want the student to do the "Kos bahan mentah" for 10 units

[ahtal68]

The "kos sampingan" given is for 10 units, so you have to calculate for one unit and then add to the total "kos bahan mentah" to get the "kos pengeluaran" for one unit which comes to RM6.90

[Jennylim]

The answer given by the authors is A.

A. RM5.90
B. RM8.90
c. RM15.90
D. RM17.70

What do you think?

[orchipalar]

Err...the correct answer is D...RM17.70.

[clfoo]

Err...the correct answer is D...RM17.70.

ini mestinya salah satu project dari BN !

[ahbitchew]

ini mestinya salah satu project dari BN !

please la have respect for BN ! such an insult to imply that BN is inefficient and no business sense, give BN more credit, if this were to be a project dari BN, the answer would have been RM177.70 !

[Jennylim]

Going by the definition:

Kos pengeluaran seunit = kos bahan mentah + kos overhed + kos upah,

if kos sampingan = kos overhed, then

Kos pengeluaran se unit= RM5.70+ RM2/10 + RM10/10 = RM6.90

So, non of the answers given in the text book is correct?

Err buddy JennyLim...the eldest of little Orchis would soon sit for UPSR too...

He too agrees with Orchi...that the answer is RM17.70...

Orchi then asked him...what if he gets it wrong also...

"Papa...getting it wrong isn't so bad...because can also learn from mistake..."

"besides when it's only 1 or 2 wrong answers...still can get A..."

Those were little Orchi's reply...

[takiro]

All the answers are correct. Depends on who is the moderator.

A. RM5.90 = bongok
B. RM8.90 = PR (risk counted)
c. RM15.90 = BN (risk + minum minum)
D. RM17.70 = Super samy (own benefit)

Cheers.

Please respect Jennylim lar.. she is trying to seek clarifications on the misprinted text book but the answer given is politically linked. This is no Arus Politik thread so please answer accordingly.

Jenny.. I strongly believe this is error in printing. Maybe you can highlight to the write via email if there is... 11 release doesn't mean no error... it is merely reprinting from the first publications with some updates, maybe.

Hmmm... interesting that you guys can argue facts like that ... i agree that it has nothing to do with politics... just as jenny said earlier... an error.. simple as that

FYI, I'm a KH teacher (somewhere) hehe... 7 years of experience in KH. From the old syllabus to this recent one... can say that it has simplified a lot of chapters...

Errors in recent KH text books? There are a few... some in questions, in the graphics, in the circuit diagrams, hmmm.... just name it. The ones that i spot on, when teaching in class, just let the students know lo... simple... dun hafta make it a fuss here.. we teachers had already made reports to PPK during our courses... Furthermore, mistakes in text books not restricted only to KH, other subjects too... if you aware, that is

Cheers in educating minds and souls

I did not just put up this thread for fun, but wonder, who do we have in MOE and what happen to the teachers? Should we just close one eye like the Melaka MP, I believe the book is being used by all schools in Petaling District! How do you expect the students to know the right and wrong when they have no earlier knowledge on the topics!

And yes, Snoopywhite, I seem to find more and more sentences and paragraphs that I have difficulty reason with logical thinking. My problem is I need to learn the topic or contents first to teach my son. Most of his schoolmates(no less than 80% of the students) did poorly in this subject, so I can't rely on the teacher.

Read the following:

3.3.3 Perbezaan Diskaun Tunai dan Diskaun Niaga

DISKAUN TUNAI

• Potongan daripada harga barang yang terdapat dalam sebut harga atau senarai harga.
• Menggalakkan pembeli membeli dalam kuantiti yang telah banyak.
• Peratusan tetap walaupun membeli dalam kadar yang lebih banyak daripada yang ditetapkan.

DISKAUN NIAGA

• Potongan wang tunai yang diberikan kepada pembeli.
• Menggalakkan pembeli menjelaskan hutang dengan segera.
• Peratusan yang diberikan lebih besar jika bayaran dibuat lebih cepat dan mungkin tidak mendapat potongan langsung jika melebihi masa yang ditetapkan.

3.3.4 Mengira Diskaun dan Syarat Pembayaran

Contoh pengiraan diskaun tunai

Harga barang dalam senarai harga ialah RM1000. Diskaun niaga yang diberikan ialah 10%. Diskaun tunai: 10% - 10 hari 5% - 30 hari

=========================================

I think the headers with the words DISKAUN TUNAI and DISKAUN NIAGA in section 3.3.3 are wrong. The two words should be exchanged to reflect the meaning of the two words in section 3.3.4 . Don’t you think so?

By the way, anyone know the meaning of “ yang telah banyak “ in section 3.3.3?
