James Ang:

My students are practising these common question types for the PSLE paper in 1 week's time.



1. John cycled at an average speed of 10km/h from his home to the park. On reaching the park, he cycled back home along the same route at an average speed of 8km/h. He took 1h 12 mins for the entire journey. How long did he take to cycle from the park back to his home?

2. Jack bought some pens and erasers for a total of $100.10. He spent $9.10 more on the pens than erasers. Each pen costs $3.70 more than each eraser. Jack bought 7 times as many erasers as pens. How much does a pen cost?

3. Andy sold thrice as many $5 T-shirts as $10 T-shirts. He also sold twice as many $10 T-shirts as $20 T-shirts. He collected $160 more from selling $5 T-shirts than from selling $20 T-shirts.

a)\tHow much money did he collect from selling $5 T-shirts?
b)\tHow many T-shirts did he sell altogether?

4. Tom and Jerry each has some money. If Tom spends $9 per day and Jerry spends $3 per day, Tom will have $100 left when Jerry has spent all his money. If Tom spends $3 per day and Jerry spends $9 per day, Tom will have $220 left when Jerry has spent all his money. How much did Jerry have?

5. A van travelled from Town A to Town B at an average speed of 55km/h. A car started its journey from town B to A at 90 km/h at the same time the van started. The two vehicles passed each other 70 km from the middle of the whole journey. Find the distance between the two towns.

6. 80% of marbles are red marbles and 20% of them are blue marbles. 63 red marbles and 46 blue marbles are added. The red marbles now makes up 75% of marbles and blue marbles 25% of marbles. How many red marbles are there at first?

7. Courier A takes 10 hours to deliver a parcel from Town X to Town Y. Courier B takes 12 hours to deliver the parcel along the same route. If the speed of Courier A is 9km/h faster than that of Courier B, find the speed of Courier A.

8. In a concert, 75% of the audience were female. 75 females and 5 males left the concert half way. The remaining audience were allocated seats in groups of 10. Each group has 3 males. How many people were in the audience at first?

9. On Linda’s birthday, she gave sweets to every pupil in her class. If she gave each pupil 7 sweets, she would have 4 sweets left. If she gave 2 sweets to each pupil, she would have 189 sweets left. How many pupils were there in Linda’s class?

10. The ratio of Ryan's pocket money to John's pocket money was 3 : 2. After Ryan saved $15 and John spent $8, the ratio of Ryan's pocket money to John's pocket money was 3 : 1. How much money did Ryan have at first?

11. A lorry left Town A for Town B. After travelling for 4 hours at its usual speed, the lorry stopped for 30 mins for a break. In order to reach Town B at the appointed time, the speed of the lorry was increased by 8 km/h. Given that the lorry took 3 hours to cover the remaining journey, find the distance between Town A and Town B.

12. Paul and Ray worked together to paint a house. During the job, Paul rested for 4 days and Ray took 2 days off. However, they were not absent on the same days. If they had done the same job alone, Paul would have taken 18 days and Ray 12 days. How long did the two painters take to complete painting the house?

Hi James,

Appreciate if you can at least give us the answers if not the full solutions. Thanks

With the PSLE result you would know where your child stand in terms of the chance of getting in. And if you already have a DSA offer, on the day after posting day you have to report to the DSA school. So if you have accepted the DSA posting and decided based on the PSLE result that you wish to go elsewhere, you have to go straight to the desired school to apply. Most likely the school will only let you know near to the posting date. Which means you have about a month's time for holiday, between results day to posting day. As for prelim results, we were not asked to produce it. Afterall you already receive the PSLE result, the appeal depends mainly on that.

Thank you, wiimum!

All the best to all P6 children :celebrate:

Accepting the DSA offer is around Oct. When the PSLE results is out, go to the IP school that you are interested to transfer to and submit your application. You would stand a much better chance if the PSLE result is not just one or 2 points above the COP along with any other support that you can garner - like prizes, awards won, leadership position etc.

After which you have to wait , from the time the PSLE result is released till the posting result is out. The IP school would inform you if you are successful in the transfer. If you do not hear from them, on the day of reporting after posting result out, you have to go to the DSA school to report. But until school reopens, there is lots of activity going on. Once transfer is successful, you need to go to the DSA school to get the letter of release and submit it to your choice school. Very tedious right?

Edited to add this: There is also the HCL letter and a letter for Third Language if the child is eligible. These will be at the DSA school after school posting results is out. You need to collect these 2 and submit the HCL letter to the school you transfer to. You need the letter for 3rd language to register at the language centre if you decide to take up the third language offer.

So my advice is still, if you could, don't transfer because it is really very troublesome and there is always the worry that your transfer is not granted. In addition, this process is very unsettling because you have to wait.... and wait (pray and pray)..... until your appeal is accepted.

Hi Wiimum,

Thanks for sharing your experience on appealing.

Can I confirm that the appeal process start right after the PSLE result day and NOT posting day? Need to know so can plan for holidays. Secondly, do they still request to see the prelim results.

Thanks in advance.

Rate of evaporation


One of the factors affecting the rate of evaporation is temperature.

When we are talking about temperature, does it refer to temperature of the source or temperature of the surroundings? For example a cup of hot water as compared to a cup of warm water in airconditioned/non airconditioned room, clothes left to dry under shade or out in the sun.
Please share your view.

Thank you for your reply

I was asked this question : why do we need to sprinkle water to clothes while ironing? Does it help to straighten the wrinkle? How?


Can anyone help?

Thank you in advance.
