(Mizoram) APEX BANK JMG 2017 reasoning Section (Number Series Based Questions)

Summary

In this educational video, the host breaks down complex number series reasoning questions, typically found in AEX Bank exams, offering a step-by-step guide to solving them. The video covers various series patterns, including arithmetic operations like division, multiplication, addition, and subtraction. The host explains how to identify the logic behind each series, such as alternating operations, using square numbers, and finding differences between terms. Additionally, they offer tips and strategies for tackling these types of questions in future exams, making it a valuable resource for anyone preparing for AEX Bank's junior management exams.

Takeaways

• 😀 The video is focused on number series-based questions from various AEX Bank exams, including 2017 and 2024.
• 😀 The script covers multiple series patterns, including arithmetic, geometric, and mixed operations like multiplication and addition.
• 😀 For the series 126, 64, 34, 20, the pattern involves dividing by 2 and adding incremental numbers, starting from 1 up to 4.
• 😀 Another example shows a difference pattern: 5, 10, 20, 40, 80, demonstrating multiplication by 2 with increasing steps.
• 😀 In the series 7, 8, 18, 57, 232, the pattern involves multiplying each number by a factor and then adding the same factor, starting from 1.
• 😀 A pattern involving multiplication and subtraction is demonstrated with the series 11, 18, 44, 76, leading to an answer of 160.
• 😀 The video explains a combination of two series with different gap patterns in the sequence 56, 6, 20, 45, 29, where alternating positive and negative operations apply.
• 😀 The approach for understanding number series is systematic, involving multiplication/division and addition/subtraction in varying sequences.
• 😀 The video suggests that the key to solving these series questions is identifying the underlying pattern, whether arithmetic, geometric, or a combination of both.
• 😀 Multiple examples are used to demonstrate how patterns can shift between addition/subtraction or multiplication/division operations, depending on the series.

Q & A

What is the main topic of the video?

The video focuses on reasoning section number series-based questions from the AEX Bank's previous exams, specifically the 2017 and 2024 question papers.

What are the key chapters discussed in the video?

The video covers fundamental reasoning chapters including logical arrangements of words and distance and directions.

What is the pattern used to solve the series '126, 64, 34, 20'?

The pattern is divided by 2 and then an increasing addition is made: divided by 2 and add 1, divided by 2 and add 2, divided by 2 and add 3, etc.

How is the number 20 in the series '126, 64, 34, 20' calculated?

The number 20 is calculated by dividing 40 by 2, then adding 4 to the result.

What operation is used to calculate the next number in the series '7, 8, 18, 57, 232'?

The pattern alternates between multiplication and addition: 7 into 1 plus 1, 8 into 2, 18 into 3 plus 3, and so on.

What is the correct answer for the next number in the series '7, 8, 18, 57, 232'?

The next number is 165, as 232 is multiplied by 5 and then 5 is added.

How is the series '11, 18, 44, 76' formed?

The series follows the pattern: multiply by 2 and subtract 4, then multiply by 2 and add 8, and continue with alternating additions and subtractions.

What is the missing number in the series '11, 18, 44, 76, ?'?

The missing number is 160, derived from the pattern: multiply by 2 and add 16.

What is the key pattern in the series '56, 6, 20, 45, 29'?

The series is a combination of two sub-series with alternating differences: one series is increasing by squares (1, 4, 9) while the other decreases based on square differences.

How is the correct answer 35 derived in the series '56, 6, 20, 45, 29'?

The answer 35 is derived from alternating negative and positive functions, with square differences leading to the result.
