- P>Q
- From second statement
- R < T
- From statement three
- Q > S > T
- From all statements
- P > Q >S >T >R
Distance & Direction
In these types of questions, assume any direction and solve the question according to that assumed direction. Assumed Direction Map should be correct. Check the distance asked in question whether it is a short distance or overall distance.
Sample Question
Vineet goes 20km north and then 21km east and then takes a 135degree turn clockwise and walks and reaches the starting point again. Find the thrice of the total distance travelled by him till he reaches the start point again?
A. 280
B. 70
C. 140
D. 210
Answer ||| D
Solution ||| He starts from A goes 20km north and 21km east and then 135-degree turn makes him face south-west and he meets point A travelling 29 km from B (by Pythagoras theorem). So total distance will be 20+21+29= 70km and thrice is 210km.
Hence, option D is the correct answer.
Missing Number
Moderate to Difficult, be careful while attempting this question. Try as many as patterns you can but fast.
Sample Question
Select the missing number from the given responses:

7×2 = 14 , 14+ 5 = 19
From second raw
6×2 = 12, 12+ 5 = 17
Similarly in third raw
5×2 = 10, 10+ 5 = 15
Hence ? = 15
