SSC CGL Direction and Distance question with solution
Direction and DistanceModerate
Neha walks 20 km towards the north, then turns and walks 21 km towards the west. How far is Neha from the starting point?
- (A)29 km
- (B)30 km
- (C)1 km
- (D)41 km
Correct answer: (A) 29 km
The two legs of the walk are at right angles, so the shortest distance from the start is the hypotenuse: √(20² + 21²) = √(400 + 441) = √841 = 29 km.
Shortcut: 20-21-29 is a Pythagorean triple.
