13 845 rounded to the nearest hundred is
1) 13 800
2) 13 850
3) 13 900
4) 14 000
Explanation
To round 13 845 to the nearest hundred, look at the tens digit, which is 4. Since 4 is less than 5, we round down. The hundreds digit (8) remains the same, and the tens and units digits become 0.
So, 13 845 rounded to the nearest hundred is 13 800.

Mrs Lee bought 9 similar packets of milk.
After she used 6 packets of milk to make some cakes, she had 3.42 L of milk left.
How many litres of milk did she have at first?
1) 6.84 l
2) 10.26 l
3) 11.58 l
4) 13.68 l
Explanation
Mrs Lee used 6 packets out of 9, so she had 9 - 6 = 3 packets left.
These 3 packets contained 3.42 L of milk.
So, 1 packet of milk = 3.42 L ÷ 3 = 1.14 L.
At first, she had 9 packets of milk.
Total milk at first = 9 packets × 1.14 L/packet = 10.26 L.

A diagram showing a series of balloons tied along a line, representing a pole. The distance between two adjacent balloons is marked as 1.65 m. A long bracket with a question mark indicates the total distance for multiple balloons.
Similar balloons are tied on a pole and placed at an equal distance.
Both ends of the pole are tied with balloons.
The distance between two balloons is 1.65 m.
What is the total distance between 8 balloons?
1) 9.9 m
2) 11.55 m
3) 13.2 m
4) 14.85 m
Explanation
If there are 8 balloons, the number of intervals between them is 8 - 1 = 7 intervals.
Each interval has a distance of 1.65 m.
Total distance = Number of intervals × Distance per interval
Total distance = 7 × 1.65 m = 11.55 m.

A rectangle labeled ABCD (A top-left, B top-right, C bottom-right, D bottom-left). A diagonal line AC is drawn. The angle ∠DAC is marked as 20°. The angle ∠BCA is marked as 60°. The angle ∠ACD is marked as X.
ABCD is a rectangle. Find ∠X.
1) 10°
2) 30°
3) 70°
4) 80°
Explanation
The diagram shows a rectangle ABCD. The angle ∠DAC is marked 20° and ∠BCA is marked 60°. The angle ∠X is marked as ∠ACD.
In a rectangle, adjacent angles sum to 90°. Therefore, ∠ADC = 90° and ∠BCD = 90°.
If ∠DAC = 20°, then in triangle ADC, ∠ACD should be 90° - 20° = 70°.
If ∠BCA = 60°, then in triangle ABC, ∠BAC should be 90° - 60° = 30°.
Also, in a rectangle, alternate interior angles are equal, so ∠ACD = ∠BAC. This would imply X = 30°.
However, the angles ∠DAC=20° and ∠BCA=60° are inconsistent for a single rectangle (since ∠DAC should equal ∠BCA if AD || BC, and 20° ≠ 60°).
Given the answer key indicates 10°, and there are inconsistencies, the most likely intended calculation (though not directly obvious from a consistent diagram) involves a subtraction from a right angle. One way to get 10° using 20° and 60° would be `90° - 20° - 60° = 10°`, assuming these angles are parts of a larger 90° angle, or other non-standard interpretation. For example, if X was the result of `∠ADC - ∠DAC - ∠DCE` for some point E. Since the question is flawed, we state the answer as per the key.

A diagram showing a piece of paper that has been folded into a complex, irregular shape. Below this, there are four options, each displaying a different symmetrical figure that could have been cut out from the folded paper.
Study the piece of folded paper. Which symmetrical figure was cut out from it?
1) A multi-pointed star/flower shape.
2) A crescent-like shape.
3) A symmetrical rounded shape with two pointed ends.
4) A four-pointed star with rounded edges.
Explanation
When paper is folded multiple times and a cut is made, unfolding it creates a symmetrical pattern. The folded paper shown has complex folds. Option (1) represents a figure that, when folded and cut in a specific way (e.g., a pointed cut at the edge), would result in a symmetrical shape with multiple 'petals' or points upon unfolding. This is a common paper-cutting activity where such shapes are generated.

Jan has 3/4 m of cloth. She has 1/2 m more cloth than Helen.
How much cloth do they have altogether?
1) 1/4 m
2) 1 m
3) 1 1/4 m
4) 2 m
Explanation
Let J be the amount of cloth Jan has and H be the amount of cloth Helen has.
Jan has 3/4 m of cloth, so J = 3/4 m.
Jan has 1/2 m more cloth than Helen: J = H + 1/2 m.
Substitute J = 3/4 m into the equation: 3/4 = H + 1/2.
To find Helen's cloth (H): H = 3/4 - 1/2 = 3/4 - 2/4 = 1/4 m.
Total cloth they have altogether = J + H = 3/4 m + 1/4 m = 4/4 m = 1 m.

How many minutes does it take for a minute hand of a clock to make 1 1/4 turn round the clock?
1) 45 min
2) 60 min
3) 75 min
4) 115 min
Explanation
A minute hand completes one full turn around the clock in 60 minutes.
1 full turn = 60 minutes.
1/4 turn = 1/4 × 60 minutes = 15 minutes.
So, 1 1/4 turns = 1 full turn + 1/4 turn = 60 minutes + 15 minutes = 75 minutes.

4) 1 h 15 min
Explanation
Start time: 11 10 (11:10 AM)
End time: 13 05 (1:05 PM)
First, calculate time from 11:10 AM to 12:00 PM:
12:00 - 11:10 = 50 minutes.
Next, calculate time from 12:00 PM to 1:05 PM:
1 hour and 5 minutes.
Total time = 50 minutes + 1 hour 5 minutes = 1 hour 55 minutes.

The area of a square is 36 cm². What is the perimeter of the square?
1) 6 cm
2) 24 cm
3) 36 cm
4) 72 cm
Explanation
The area of a square is given by the formula side × side (s²).
Given Area = 36 cm², so s² = 36 cm².
To find the side length (s), take the square root of 36: s = √36 = 6 cm.
The perimeter of a square is given by the formula 4 × side (4s).
Perimeter = 4 × 6 cm = 24 cm.

A line graph titled 'Sales ($)' vs 'Time'. The y-axis shows sales from 0 to 5000 in increments of 1000. The x-axis shows time from 5 p.m. to 10 p.m. The line plot shows sales changing over these hours: 5 p.m. (~$1500), 6 p.m. (~$2500), 7 p.m. (~$4500), 8 p.m. (~$3500), 9 p.m. (~$1500), 10 p.m. (~$500).
The graph below shows the hourly sales at a departmental store on Saturday.
During which one-hour interval had the greatest decrease in sales?
1) 6 p.m. to 7 p.m.
2) 7 p.m. to 8 p.m.
3) 8 p.m. to 9 p.m.
4) 9 p.m. to 10 p.m.
Explanation
Read the sales values from the graph for each hour:
5 p.m.: $1500
6 p.m.: $2500
7 p.m.: $4500
8 p.m.: $3500
9 p.m.: $1500
10 p.m.: $500
Calculate the change in sales for each interval:
1) 6 p.m. to 7 p.m.: $4500 - $2500 = $2000 (increase)
2) 7 p.m. to 8 p.m.: $4500 - $3500 = $1000 (decrease)
3) 8 p.m. to 9 p.m.: $3500 - $1500 = $2000 (decrease)
4) 9 p.m. to 10 p.m.: $1500 - $500 = $1000 (decrease)
The greatest decrease in sales is $2000, which occurred from 8 p.m. to 9 p.m.

A two-part image. The top part is a table showing Jean's Sunday activities and their start times: Wake up (08:00), Breakfast (08:15), Art and Craft (08:50), Watch TV (10:50), Play computer games (start time missing), Lunch (13:25). The bottom part shows two diagrams related to paper pasting. 'Before pasting' shows two separate 10 cm x 10 cm squares. 'Figure formed' shows these two squares overlapping, with the overlap creating a 5 cm x 5 cm square in the center. The overall dimensions of the formed figure are 15 cm (length) and 10 cm (width).
