Tips
Tip 1: Have an Objective Approach
When you see a question, do the following:
Read the question and the options given
Choose the less time-consuming method
Solve the question
Six persons P,Q,R,S,T and U sit around a circular table with equal distance between neighbours. P is to the immediate left of R. T and S do not sit next to each other, and T and R are diametrically opposite to each other. Which of the following is NOT possible? (CSIR NET FEB 2022)
Q and P are sitting diametrically opposite to each other
Q and P are sitting diametrically opposite to each other: This is possible. We can place Q and P in two opposite seats.
P and U are sitting diametrically opposite to each other
P and U are sitting diametrically opposite to each other: This is possible. We can place P and U in two opposite seats.
S and T are sitting diametrically opposite to each other
S and T are sitting diametrically opposite to each other: This is not possible because T and R are already diametrically opposite to each other.
S and Q are sitting diametrically opposite to each other
S and Q are sitting diametrically opposite to each other: This is possible. We can place S and Q in two opposite seats.
Tip 2: Time factor
2 minutes – Maximum Time for any question
30 minutes – Maximum Time for Part A Section
Assign Time for Part A, Part B and Part C
Tip 3: Choose the Right Method
Practice makes it perfect! Train yourself to choose the right method to solve the question in the shortest time. Read Session 2 Notes or Buy the Book for more details.
A and B complete a work in 30 days. B and C complete the same work in 24 days whereas C and A complete the same work in 28 days. Based on these statements which of the following conclusions is correct? (CSIR-NET NOV 2020)
C is the most efficient and B is the least efficient.
Try again!
B is the most efficient but the least efficient one cannot be determined.
Try again!
C is the most efficient but, the least efficient one cannot be determined.
Try again!
C is the most efficient and A is the least efficient.
Time taken by C to complete the work = 45.4 days
Time taken by A to complete the work = 73 days
Time taken by B to complete the work = 50.9 days
Tip 4: Choose the Right Question
Approximate Question Distribution
Easy questions: 7 to 8
Medium level questions: 5 to 6
Difficult questions: 7 to 8
Train yourself to identify the difficulty of the question in the shortest time!
