If you searched for a WPLN practice test PDF with questions and answers, this is it — and it is genuinely free. Most of what comes up for that search sits behind a document-sharing site that wants an account first. This one downloads on the next tap.
20 original WPLN-style numeracy questions, plus an answer key with the working for every one and the mistake each question is designed to catch.
⬇ Download the free PDFThe worksheet is in two parts. Part 1 is the 20 questions with a line under each one to work on. Part 2 is the answer key — and it is the part worth spending time in, because each answer shows the full working and names the slip that question was built to catch. Getting a question right for the wrong reason is the thing that catches people out on the day.
It was written by a Singapore parent preparing his own son for the WPLN, which is why the questions use hawker centre bills, bus fares, shift hours and NTUC prices rather than abstract sums.
Every question from the PDF is below as well, so you can work through them here without downloading anything. Tap Show the answer and working when you want to check.
At a hawker centre Mei buys chicken rice for $4.50, an iced kopi for $1.80 and a kaya toast set for $3.20. How much does she spend altogether?
Answer: $9.50
Add the three prices: $4.50 + $1.80 = $6.30. Then $6.30 + $3.20 = $9.50.
Common slip: A common slip is adding the dollars and cents separately and losing the carry from 50c + 80c.
Mei pays for her $9.50 meal with a $20 note. How much change should she get?
Answer: $10.50
$20.00 − $9.50. Take away $9 to get $11.00, then take away the last 50c: $10.50.
Common slip: Counting up from $9.50 to $20 works just as well, and is easier to do in your head.
A packet of rice crackers costs $1.35. Raj buys 3 packets. What is the total cost?
Answer: $4.05
$1.35 × 3. Three lots of $1 is $3, three lots of 35c is $1.05. $3 + $1.05 = $4.05.
Common slip: 35c × 3 = 105c, which is $1.05 — not 5c with the dollar forgotten.
A 500 ml bottle of drink costs $1.60. A 1.5 litre bottle of the same drink costs $4.20. Which one costs less per litre?
Answer: The 1.5 litre bottle ($2.80 per litre vs $3.20 per litre)
500 ml is half a litre, so the small bottle is $1.60 × 2 = $3.20 per litre. The large bottle is $4.20 ÷ 1.5 = $2.80 per litre. The 1.5 litre bottle is better value.
Common slip: The bigger bottle costs more in total — but the question asks about cost per litre.
A pair of shoes costs $45. There is a 20% discount. What is the new price?
Answer: $36
20% of $45 is $45 ÷ 5 = $9. New price = $45 − $9 = $36.
Common slip: $9 is the discount, not the price. The question asks what you actually pay.
Raj's bus leaves at 7:45 am. The journey takes 35 minutes. What time does he arrive?
Answer: 8:20 am
From 7:45 it is 15 minutes to 8:00. That leaves 35 − 15 = 20 minutes more, so 8:20 am.
Common slip: 7:45 + 35 is not 7:80. Time rolls over at 60 minutes, not 100.
Siti's shift runs from 9:00 am to 5:30 pm, with a 45 minute unpaid lunch break. How many hours does she actually work?
Answer: 7 hours 45 minutes
9:00 am to 5:30 pm is 8 hours 30 minutes. Take off the 45 minute break: 8 h 30 min − 45 min = 7 h 45 min.
Common slip: Forgetting to subtract the break gives 8 h 30 min — the most common error on pay questions.
A movie starts at 2:15 pm and runs for 1 hour 50 minutes. What time does it end?
Answer: 4:05 pm
2:15 pm + 1 hour = 3:15 pm. Then + 50 minutes: 45 minutes takes you to 4:00 pm, and 5 minutes more makes 4:05 pm.
Common slip: Adding 1.50 instead of 1 hour 50 minutes gives 3:65 — which is not a time.
Trains leave every 12 minutes. The first train is at 6:00 am. What time does the 5th train leave?
Answer: 6:48 am
The 1st train is at 6:00, so the 5th train is 4 gaps later, not 5. 4 × 12 = 48 minutes. 6:48 am.
Common slip: Multiplying 5 × 12 gives 7:00 am. Count the gaps between trains, not the trains.
In the number 47.63, what is the value of the digit 6?
Answer: 6 tenths (0.6)
After the decimal point the first place is tenths. The 6 sits there, so it means 6 tenths, or 0.6. The 3 is 3 hundredths.
Common slip: Saying "6" or "6 hundredths" — position is what gives a digit its value.
What is 12.5 + 3.75?
Answer: 16.25
Line up the decimal points and write 12.5 as 12.50. 12.50 + 3.75 = 16.25.
Common slip: Lining the numbers up on the right instead of on the point turns 12.5 into 12.05.
What is 8.4 − 2.65?
Answer: 5.75
Write 8.4 as 8.40 so both have two decimal places. 8.40 − 2.65 = 5.75.
Common slip: Without the extra zero it is easy to take 2.65 from 8.04 by mistake.
What is 3/4 of 60?
Answer: 45
Divide by the bottom, multiply by the top. 60 ÷ 4 = 15, then 15 × 3 = 45.
Common slip: Doing 60 ÷ 3 × 4 = 80 — the bottom number is the one you divide by.
What is 25% of $84?
Answer: $21
25% is the same as one quarter. $84 ÷ 4 = $21.
Common slip: 25% does not mean "take off 25 dollars".
A pencil is placed on a ruler. One end is at the 2 cm mark and the other is at the 11.5 cm mark. How long is the pencil?
Answer: 9.5 cm
Length is the difference between the two marks: 11.5 − 2 = 9.5 cm.
Common slip: Reading off 11.5 cm — that is where the end sits, not how long the pencil is, because it did not start at 0.
A bag of rice holds 5 kg. A recipe uses 250 g each time. How many times can the bag be used?
Answer: 20 times
5 kg is 5000 g. 5000 ÷ 250 = 20. Converting to the same unit first is the key step.
Common slip: Dividing 5 by 250 without converting — the units have to match before you divide.
A room is 4.5 m long and 3 m wide. What is its area?
Answer: 13.5 m²
Area = length × width = 4.5 × 3 = 13.5 m².
Common slip: 4.5 + 3 = 7.5 m is the wrong operation — that is halfway to the perimeter, not the area.
A stall's takings from Monday to Friday were $120, $95, $140, $105 and $90. What were the average daily takings?
Answer: $110
Add them: $120 + $95 + $140 + $105 + $90 = $550. Then divide by the number of days: $550 ÷ 5 = $110.
Common slip: Dividing by 7 because it feels like a week — divide by how many numbers you actually added.
Danial saves $12 every week. How many weeks will it take him to save $150?
Answer: 13 weeks
$12 × 12 weeks = $144, which is not quite enough. After 13 weeks he has $156, so 13 weeks is the answer.
Common slip: $150 ÷ 12 = 12.5, and you cannot save for half a week — round up, not down.
There are 28 students in a class. 3/7 of them take the bus to school. How many students do NOT take the bus?
Answer: 16 students
3/7 of 28: 28 ÷ 7 = 4, then 4 × 3 = 12 students take the bus. Those who do not: 28 − 12 = 16 students.
Common slip: Stopping at 12 — read the question again, it asks for the ones who do NOT take the bus.
A worksheet has one weakness — 20 fixed questions, and once they are memorised they stop teaching anything. Our free online practice generates fresh WPLN-style questions every session, marks each one instantly and shows the working, so the same skill can be practised as many times as it takes.

There is also a full page of tap-to-answer money questions, and the complete numeracy practice app with daily sessions and progress tracking.
Yes. This page has a free WPLN numeracy practice PDF with 20 original questions and a full answer key showing the working for every one. It downloads straight away — no sign-up, no email address and no payment.
No. The PDF downloads directly from this page with no form of any kind. We built it to be useful, not to collect addresses.
Twenty questions across the everyday maths the WPLN numeracy paper draws on: money and change, best value, discounts, time and shift hours, timetables, decimals and place value, fractions and percentages, measurement and area, averages, and word problems.
Yes, please do. It is formatted for A4 with space to write under each question. Teachers, tutors, carers and parents are welcome to print and copy it for their own learners.
No, and you should be careful of anything claiming to be. Every question here is our own original work, written to resemble the style and difficulty of the WPLN numeracy paper. They are for familiarisation and practice, not a reproduction of any official assessment.
Yes. The worksheet has 20 fixed questions; our free online practice generates fresh WPLN-style questions every session and marks them instantly, so the same skill can be practised repeatedly rather than memorised from one answer sheet.
