Bodhak competitive bank exams direction in this chapter we will discuss DIRECTIONS. We will see how o solve through equations and through shortcut methods
competitive bank exams direction
In directions, there are 8 directions.
There are three types of models in directions.
1: Distance problems
2: Left-Right problems
3: Shadow problems
In directions the following table is important
Here we find the distance between starting and ending points
1.If two directions are same then added: N+N,S+S,E+E,W+W.
2.If two directions are opposite then subtracted: N-S,E-W.
3.If two directions are neither same nor opposite then apply Pythagoras rule.
Sachin starts his journey from his house towards ground. First he walk 7km towards north then turns East and walks 12km and then turns north and walks 3km then turns west and walk 15km then turns south and walks 10km and reaches to the ground. Then what is the distance between house and ground.
Step 1: write down the directions and distances
NORTH-7 EAST-12 NORTH-3 WEST-15 SOUTH-10
Step 2: If two directions are same then add
NORTH-7+3 EAST-12 WEST-15 SOUTH-10
Step 3 : if two directions are opposite then subtract
NORTH-10 EAST-12 WEST-15 SOUTH-10 =WEST 15-EAST12 = WEST 3KM
Here we have 4 types of questions
1) What was the total journey
Add All directions :NORTH-7 EAST-12 NORTH-3 WEST-15 SOUTH-10 = 47km
2) What is the distance between starting point & end point
NORTH-10 EAST-12 WEST-15 SOUTH-10 =WEST 15-EAST12 = 3KM
3) In which direction is he from the starting point
NORTH-10 EAST-12 WEST-15 SOUTH-10 =WEST 15-EAST12 = WEST
4) In which direction is he from the ending point
Opposite to west i.e EAST
