Correct Answer: D
Net displacements: North = 3 km, East = 4 - 3 = 1 km. Distance from origin = √(3² + 1²) = √10 ≈ 3.16 km.
Q3.Jason owns 35 spatulas. Some are purple, some are turquoise and several are black. One seventh are orange. Are 5 spatulas definitely orange?

Q4.All daffodils are plants. All plants are living things. Some living things are real. Conclusions: I. All daffodils are living things. II. Some living things are flowers. III. All daffodils are real. Which conclusions follow?
Correct Answer: A
Conclusion I is true because daffodils are plants, and all plants are living things. Conclusion II is invalid because the premises do not mention flowers. Conclusion III is invalid because we only know some living things are real, which does not guarantee daffodils are real.
Q5.A man walks 3km northwards and then turns left and goes 2 km. He again goes left and walks 3 km. He turns right and walks straight. In which direction he is walking?

An upright person facing south has their left hand pointing East. Standing upside down flips the vertical axis but preserves the relative left/right direction of hands relative to facing. Left hand still points East.
Q7.A person travels 12 km north, then 15 km east, 15 km west, and finally 18 km south. How far is he from the starting point?
Correct Answer: C
Net East-West movement = 15 - 15 = 0 km. Net North-South movement = 12 km North - 18 km South = 6 km South. Distance = 6 km.

Q9.I went 15 km to the North, then turned West and covered 10 km. Then I turned South and covered 5 km, and then I turned East and covered 10 km. In which direction am I going and how far from starting point?
Correct Answer: B
North 15 km, then South 5 km results in a net displacement of 10 km North. West 10 km and East 10 km cancel each other out. Thus, you are exactly 10 km North of the starting point.
Q10.You travel 4 km south from your home to meet your friend. To return home, you should travel?
Correct Answer: B

Q11.Ali walks 5km east, then 4 km north, How far is he from starting point?

Q12.Ali walk 10 meter to north, turn right and walk 5 meter , turns right again and walk 10 meter. What is his distance and direction from his starting?
Correct Answer: D
Ali moves 10 m North, then 5 m East (right), then 10 m South (right again). The North-South movements cancel out, leaving him exactly 5 meters East (to the right) of his starting point.
Q13.If a man faces north, then turns left, and again turns left, what is his current direction?
Correct Answer: D
Starting facing North: First left turn leads to West. Second left turn leads to South. So the current direction is South.
