2010 PSLE Math Solutions
2010 PSLE SOLUTIONS fresh from the oven (7 Oct 2010)
These few questions were texted to our mobiles by our students. The following solutions for all to check if they got them right. Our solutions are correct according to the questions provided by our students based on pure memory (the questions were accurate as we have double-checked with other sources). Hope you have done Exceptional well!
(Paper 2, Q18)
There are 2 tanks A and B. Tank A is 60 x 10 x 40 cm and Tank B is 50 x 20 x 36 cm. Tank B is 1/3 filled with water. Two similar taps are turned on to fill both tanks at 1.2 litres per minute. How long does it take for the height of water in both tanks to be the same?
Solution:
A base area = 60 x 10 = 600 cm2
B base area = 50 x 20 = 1000 cm2
When water flows in at 1.2 ℓ per minute the height will rise differently for both tanks.
Tank A’s height per minute = 1200/600 = 2 cm / min
Tank B’s height per minute = 1200/1000 = 1.2 cm / min
Let time be m when height of water in both tanks become the same;
2 x m = 1.2 x m + 12 cm (1/3 filled at first)
2m = 1.2m + 12
0.8m = 12
m = 15 mins

Gary and Fadzil were in a race. When Gary finished the race, Fadzil had completed 5/8of the race. Gary’s speed is 75m/min faster than Fadzil’s. If their speeds were not changed throughout the race, what is Fadzil’s speed?
.........G F
Dist...8u 5u
Speed 8u 5u
Speed diff = 3u = 75m/min
1u = 25m/min
So, F speed = 5u = 5 x 25 = 125m/min
(Paper 2, Q11)
There are 320 marbles and they are placed into box A, B, C, D. A has the most number of marbles while D has the least number of marbles. The difference of A and the other boxes are 8,13 and 19. How many marbles are there in box D?
A = A; B = A – 8; C = A – 13; D = A – 19
Total = 4A – 40 = 320
4A = 360
A = 90
D = 90 – 19 = 71
(Paper 2, Q16)
Nurul and Peili have $60 altogether. They went shopping and Nurul spent twice as many as Peili. The amount of money Peili left was $7 more than the amount she spent. In the end, Peili had twice as much money as Nurul.
a) How much money did Peili spent?
b) How much money did Nurul had at first?
Model:<----left-----> <------ spent----->
N -> ........[0.5x+3.5][ x ][ x ]
P -> [<---x +7----> ][ x ]
N = 0.5x + 3.5 + 2x
P = 2x + 7
Total = 4.5 x + 10.5 = 60
4.5 x = 49.50
x = 11
a) P spent = $11
b) N at first = 2.5x + 3.50
= 2.5 x 11 + 3.5
= $31

CYBER-BULLIED ON CHILDREN’S DAY 2010
1 October is Children’s Day. It was supposed to be a happy day but we were not happy. As we gave out Children Day gifts, someone threw us a stinkbomb on KiasuParents.com’s forum, a popular parenting website. The vicious comments were subsequently embargoed by the site’s administrator as it was considered a personal vendetta by a disgruntled customer.
We need to set the record straight as some members of the public have seen the bad-mouthing by the suspect.
We suspect the post by a “Goldman” in the Kiasuparents forum was made by a disgruntled and highly agitated parent whom we refused his child's admission to our programme. This is because we found the potential customer to be unduly demanding and irrational. A parent who called us (rudely) at least 5 times just to get the address right and asked "difficult" questions that left us dumbfounded.
We were uncomfortable with his demeanor. There are concerns that we may not be able to meet up to his possible unusual requests and expectations, that may interfere with the way we run our classes. Based on experience, it is better not to accept such customers in the first place.
We feel that it is our responsibility to provide a conducive and happy environment for our existing students. We did the unthinkable. We rejected him.
Customer is king. We suppose it may be a case of inability of handling the truth and the suspected customer probably went berserk and went all out to bad mouth with the aim to destroy us.
On 30 September, we had a last conversation to reject this potential customer. And immediately on 1 Oct (Children’s Day), we discovered from Kiasuparents.com that we had been flamed under all references to us, viz Scharff and VIP learning. We suspect that "Goldman" is the same parent that we had rejected on 30 September. If so, we feel sorry for the child as the child didn’t get to attend a single lesson?!
We quote the late Mrs Lee Kuan Yew: “Sometimes without doing bad things, people will say bad things about you.”
We impressed on our students the importance of responsibility. Each and everyone of them can succeed when they hold themselves responsible for their learning.
As educators, we are responsible to ensure that they learn in a conducive, enjoyable and effective environment, on top of imparting proper techniques and approaches to problem solving in Mathematics. We partner with their parents to ensure continuity in the learning process at home. We value the strong relationships we established with the parents as they play the crucial role in tightening possible slack in the technique mastery process.
We hold ourselves responsible in providing a conducive and happy environment to our existing students and their parents. In very rare situation, we reserve the right to refuse entry to any potential customers that display irrational behaviour and present unreasonable demands that may disrupt the progress of the class.
We cannot allow our name to be wrongly tarnished by "Goldman". As such, we filed a police report on 3 October, 8 pm at Chong Pang Neighbourhood Police Post. This is to register the truth with the Authority and should the suspect continue his irrational behaviour, we will consider taking legal actions.
May the good prevail!
