Swetha starts from her office and walks 150 m towards south, then she turns right and walks 80 m and then she turns left and walks 60 m. She finally turns left and walks 280 m to reach a bank. What is the shortest distance between her office and the bank?
A. 290 m
B. 280 m
C. 370 m
D. 410 m
Answer: Option A
Solution (By JKExamLibrary)
Vertical movement: 150 m South + 60 m South = 210 m South. Horizontal movement: 80 m West, then 280 m East = 200 m East. The shortest distance is the hypotenuse: √(210² + 200²) = √(44100 + 40000) = √84100 = 290 m.
Mohan walks 5 m towards East and then turns to his right, walks 4 m and then again turns to his right and walks 5 m. Now he takes a left turn and walks 20 metres. He again takes a right turn and walks an additional 20 meters to reach the theatre. In which direction is the theater with respect to Mohan's starting point?
Explanation:
Path: 5m East, 4m South (right), 5m West (right). He is now 4m South of start. Then he turns left (South) for 20m (total 24m South), then right (West) for 20m. Final position is 20m West and 24m South of the starting point, which is South-West.
Explanation:
Normally, if a person stands upright facing East, their right hand points South. In a headstand posture (upside down), the left and right orientation is reversed. Therefore, his right hand will point towards the North.
