Ender Hypersonic July 15, 2016 Share July 15, 2016 Swapping 2 tens for 2 twos would cause the number of tens to decrease by 2 and the number of twos to increase by 2. I think this is where we interpret differently.. To me swap 2 tens to 10 twos to maintain the same value. I guess the question wasn't specific. In most PSLE questions, they will specifically says the swap will maintain the same value. ↡ Advertisement Link to post Share on other sites More sharing options...

Well, if that was the intent this was a terribly worded question or it wasn't transcribed properly here. If I saw it written that way in the exam I would have gone with my reckoning. Simply because they didn't invoke the values of the notes till the last line. Edited July 15, 2016 by Turboflat4 Link to post Share on other sites More sharing options...
Ender Hypersonic July 15, 2016 Share July 15, 2016 Well, if that was the intent this was a terribly worded question or it wasn't transcribed properly here. having gone thru hundreds PSLE questions with my son last year. 99% of them will specifically word to says the the swap for same value. This question belongs to the one percent. Link to post Share on other sites More sharing options...
1fast1 Supersonic July 15, 2016 Share July 15, 2016 (edited) I would ask @Hiphiphoray to please post the original questions in their exact wording. The funfair one was poorly phrased too, but the intent was possible to discern (unless you allow transgender students!).

Hiphiphoray 6th Gear July 15, 2016 Share July 15, 2016 Penty of schools' semester exams have lousy questions. At least now we know there can be 2 answers....hehehe I would ask @Hiphiphoray to please post the original questions in their exact wording. The funfair one was poorly phrased too, but the intent was possible to discern (unless you allow transgender students!). Can show model style workings? Or does psle marking scheme accept such workings? having gone thru hundreds PSLE questions with my son last year. 99% of them will specifically word to says the the swap for same value.

Psle no need to know for now but its good to know from experts like you. Oh P3, than no choice, have to use modelling, they are strict in using modelling for p3 and p4. Only in P5 onwards they will be shown the using of 'u' in place of drawing boxes. And by P6, they should have been taught to use two variables , 'u' and 'p' Edited July 15, 2016 by Ender 1 Link to post Share on other sites More sharing options...

Hiphiphoray 6th Gear August 8, 2016 Share August 8, 2016 A Pen costs 95 cents more than a Pencil Catherine bought twice as many Pencils as Pens. She spends a total of $53.60. She spent $2.40 more on Pens than Pencils. How many Pens did Catherine buy ? Link to post Share on other sites More sharing options...
Ender Hypersonic August 8, 2016 Share August 8, 2016 Total spending of pencils =(53.6 -2.4)/2 = $25.60 Total spending on pens = $25.60 +. 2.4 = $28 Since ratio of pencils : pens => 2:1 Pencils is 2u Pens is 1u 1u of pencils cost= 25.6/2 = $12.80 1u of pens cost $28 Difference = 28 - 12.8 = 15.2 1u = 15.2/ 0.95 = 16 Pen is 1u = 16### 4 Link to post Share on other sites More sharing options...

Topspin 2nd Gear August 10, 2016 Share August 10, 2016 Hi All Anyone knows how to solve this P6 math question? Is this really a PSLE question? To solve this I think you will need to use the area of a sector and Pythagorean theorem which is beyond PSLE level. Link to post Share on other sites More sharing options...
Rayleigh 6th Gear August 10, 2016 Share August 10, 2016 Unfortunately it is. Link to post Share on other sites More sharing options...
Topspin 2nd Gear August 10, 2016 Share August 10, 2016 Unfortunately it is. The answer is a quarter (0.25). I used area of a sector to get the answer. I do not know of any other ways to solve it. For PSLE standard, they only learned how to calculate area of a sector in a quarter (90 deg) or a semicircle (180 deg) In your drawing, the angle of the sector is 120 deg and to get this 120 deg, I need to use cosine. Definitely an O level type of question, not PSLE. 1 Link to post Share on other sites More sharing options...
daggyr 1st Gear August 10, 2016 Share August 10, 2016 Hi All Anyone knows how to solve this P6 math question? Probably like this unshaded A = 1/4 unshaded B = 3/12 = 1/4 total unshaded =1/4 ↡ Advertisement 8 Link to post Share on other sites More sharing options...
