Gaeta walks 20 m towards north, then she walks 12 m towards the South. Now, she walks 6 m towards east. How far and in which direction is she from the starting point?
Answer (Detailed Solution Below)View answer ▾Hide ▴
Answer: Option A — 10 m North-East
Detailed Solution
Walking 20 m north and then 12 m south leaves her m north of the start.
The 6 m east walk puts her 8 m north and 6 m east of the start.
Distance m, in the north-east direction.
✓ Check
6, 8, 10 is a right triangle: .⚠ Common trap
Option (B), 10 m North, has the right distance but the wrong direction, because the 6 m east walk moves her sideways; option (C), 6 m East, ignores the 8 m northward displacement.Quick tip

Direction Sense — Preparation
This question tests your understanding of Direction Sense, a key topic in the Logical Reasoning section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
Direction sense questions describe a person's movements, such as walking 5 km north and then turning right, and ask for the final direction or distance from the starting point. This topic covers the four main and four intermediate directions, left and right turns, shadow-based questions using the position of the sun, and coded direction questions. Always draw a rough diagram as you read each step. For the shortest distance between the start and end points, use the Pythagorean theorem on the net north-south and east-west distances. Remember that the sun rises in the east, so in the morning a person's shadow falls to the west, and in the evening it falls to the east. A right turn from north points east, and a left turn from north points west. Practise the direction sense questions below, each with a step-by-step diagram solution.
