Which statement about parallel lines is true?

A. They are always curved.
B. They are always the same distance apart.
C. They always cross each other.
D. They form a right angle when they meet.

✅ Answer: B

Parallel lines are defined as lines that are always the same distance apart and never meet. Option C is wrong (describes intersecting lines). Option D is wrong (describes perpendicular lines). Option A is wrong (lines are straight in this context).

A square photo frame has a side of 12 cm. Mrs Lee wants to put a border around the frame. What is the length of the border she needs, and what is the area of the photo frame?

A. Border: 48 cm, Area: 144 cm²
B. Border: 144 cm, Area: 48 cm²
C. Border: 48 cm, Area: 24 cm²
D. Border: 24 cm, Area: 144 cm²

✅ Answer: A

The length of the border is the perimeter of the square: 4 × 12 cm = 48 cm. The area of the photo frame is Side × Side: 12 cm × 12 cm = 144 cm². Options B, C, and D confuse the calculation methods for area and perimeter or their resulting values.

Mrs Lim used 1/6 of a bag of flour to bake a cake and 2/6 of the same bag of flour to make some cookies. What fraction of the bag of flour did she use in total?

A. 1/6
B. 2/6
C. 1/2
D. 3/12

✅ Answer: C

To find the total flour used, add the fractions: 1/6 + 2/6 = 3/6. Then, simplify 3/6 by dividing both numbers by 3, which gives 1/2. Option D is wrong because it incorrectly adds both the numerators and denominators.

John cycles 2 km 300 m from his home to the park. He then cycles 1 km 800 m from the park to the library. What is the total distance John cycles?

A. 4 km 100 m
B. 3 km 100 m
C. 4 km 500 m
D. 3 km 500 m

✅ Answer: A

Add the metres first: 300 m + 800 m = 1100 m. Since 1000 m = 1 km, this is 1 km 100 m. Add the kilometres: 2 km + 1 km + 1 km = 4 km. So the total is 4 km 100 m. Option B makes an error in carrying over kilometres.

There are 4 boxes of apples. Each box contains 120 apples. How many apples are there in total?

A. 400
B. 360
C. 124
D. 480

✅ Answer: D

To find the total number of apples, multiply the number of boxes by the number of apples in each box: 4 × 120 = 480. Option C shows an addition error (120+4), while Option A might be a simple estimation or rounding error.
