Today we’ll discuss about Direction Sense. This topic is can fetch you marks easily but you need to know the right concepts and types of questions to practice.
➀ Read the instructions of the question carefully and mark the points and make a diagram for reference. This will save your time while solving the questions and help you in maintaining accuracy.
Example: Yashita and Sahil are two friends walking in a maze garden. Yashita is on a mark Q and moves ahead in north for 8 meters to point R, then she takes a left turn and after walking 6 meters reaches point S. She now takes a right turn 4 meters reaches point T, then she takes a left turn and after 6 meters reaches point U and she sits down to take some rest. Meanwhile Sahil who is at point B which is 4 meters to the south of point U, walks 8 meters south and takes a left turn and after walking 6 meters reaches point P and rests there.
➁ Concept of shortest distance: Application of Pythagoras theorem
exit point of the maze garden which apparently Yashita had missed and walked
past the point. Sahil recognised it and walks the shortest distance from his
resting point and exits the maze garden. How much has he walked from his starting
to get the answer of this question we have to find the distance PR. We can see PQR
forms a right angled triangle and hence Pythagoras Theorem can be applied to
it. The theorem states that Hypotenuse =
sq. root ( (Base)2 + (Perpendicular)2)
