Reasoning
A person walks 5 km north, then 3 km east, then 2 km south. How far and in which direction is he from the starting point?
Net north = 5 - 2 = 3 km Net east = 3 km Distance = √(3² + 3²) = √18 = 3√2 km Direction = Northeast

Correct answer: 6 days
Quantitative
A train 150 meters long passes a pole in 15 seconds. What is its speed in km/hr?
Distance = 150 meters = 0.15 km Time = 15 seconds = 15/3600 hours = 1/240 hours Speed = Distance/Time = 0.15 / (1/240) = 0.15 × 240 = 36 km/hr
Quantitative
