Summary

TLDRIn this video, the instructor presents a logical reasoning question based on letter pairs in the word 'shutdown'. The challenge is to identify pairs of letters where the number of letters between them in the word matches the number of letters between them in the English alphabet, both forwards and backwards. The instructor provides a step-by-step breakdown of the solution, identifying valid pairs like 'S to U', 'H to N', and 'T to W'. He also highlights the increasing trend of diverse question types in exams like GATE and promotes his courses for further learning and preparation.

Takeaways

  • 😀 The question in the script is a logical reasoning problem from the 2025 GATE exam, focusing on finding letter pairs in the word 'shutdown' that follow a specific pattern.
  • 😀 The task is to identify pairs of letters in 'shutdown' where the number of letters between them is the same as in the English alphabet, both forward and backward.
  • 😀 The method to solve the problem involves using a diagram where the word 'shutdown' is written, and each letter pair is analyzed for the required pattern.
  • 😀 The reasoning for each pair starts by examining letters one by one, beginning with 'S', and checking if the number of elements between them matches the condition in the alphabet.
  • 😀 Some pairs, like 'S to U', satisfy the condition of having one letter in between both in the word and in the English alphabet.
  • 😀 Other pairs, like 'S to T', 'S to D', and 'H to T', do not meet the required condition because they have too many or too few elements in between.
  • 😀 After going through each letter in 'shutdown', the solution concludes that there are exactly four valid pairs of letters that satisfy the condition.
  • 😀 The final valid pairs are: 'S to U', 'H to N', 'T to W', and 'H to T'.
  • 😀 The solution emphasizes the importance of understanding logical reasoning concepts and suggests using diagrams for such problems.
  • 😀 The speaker also promotes the Shen Jan Study Simplified app for further learning, which includes recorded classes, doubt-solving groups, and affordable courses for GATE preparation.

Q & A

  • What is the main objective of the logical reasoning question discussed in the video?

    -The main objective is to find how many pairs of letters exist in the word 'shutdown' where the number of letters between each pair in the word is the same as in the English alphabetical series, both forward and backward.

  • What method does the speaker recommend for solving this type of logical reasoning question?

    -The speaker recommends creating a diagram by writing out the word 'shutdown' and systematically checking each letter pair to see if they satisfy the condition of having the same number of letters between them, both in the word and in the alphabet.

  • What was the first letter pair checked in the solution, and what was the result?

    -The first letter pair checked was 's' to 'h'. It was found that there are no elements in between them, so this pair does not satisfy the condition.

  • Why is the 's' to 'u' pair considered valid?

    -The 's' to 'u' pair is valid because there is one element between 's' and 'u' in both the word 'shutdown' and the English alphabetical series.

  • What condition was not satisfied for the 's' to 't' pair?

    -The condition was not satisfied for the 's' to 't' pair because there were no elements in between them in the word, while there are two elements between 's' and 't' in the English alphabetical series.

  • How does the speaker verify the pairs between the letters in the word 'shutdown' and the English alphabet?

    -The speaker compares the number of letters between each pair in the word 'shutdown' and checks whether the same number of letters appear between the corresponding letters in the English alphabet, both forward and backward.

  • What is the final answer to the logical reasoning question?

    -The final answer is option C, which states that there are four valid letter pairs in the word 'shutdown' that satisfy the given condition.

  • Which letter pairs in the word 'shutdown' did not satisfy the given condition?

    -The pairs 's' to 'd', 's' to 'o', 's' to 'w', 's' to 'n', 'h' to 'u', 'h' to 'd', 'h' to 'o', 'h' to 'w', 'h' to 'n', and several others were not valid because they either had too many or too few elements between the letters compared to their positions in the English alphabet.

  • What is the significance of checking the letter pairs in both forward and backward alphabetical order?

    -Checking both forward and backward alphabetical order ensures that the condition applies in all possible directions, which adds complexity and ensures that the correct valid pairs are found.

  • What does the speaker suggest for students who may find such logical reasoning questions challenging?

    -The speaker suggests that students who find such questions difficult should use the Shen Jan study simplified app, where they can find recorded classes, doubt-solving groups, and study materials tailored for GATE preparation.
