AI Summary

An AI-generated summary of this video lecture.

This video is a lecture on solving calendar-based aptitude questions, presented by an instructor from Knowledge Gate. The session begins with a question asking for the date 89 days from January 20, 2017, a Sunday. The instructor breaks down the calculation by first determining the number of weeks and remaining days, using the formula 89 = 12*7 + 5, which results in 12 weeks and 5 days. He then calculates the day of the week by adding 5 days to Sunday, concluding it is a Friday, and identifies the date as April 19, 2017. The second problem involves a 30-day month starting on a Saturday, with specific holidays on every second and fourth Saturday and all Sundays. The instructor calculates the total number of holidays (7) and subtracts this from the total days to find 23 working days. The final problem states that the second day of a month is a Sunday and asks for the last day of the next month, which has 31 days. The instructor deduces that the first day of the month is a Saturday, and by counting forward, determines the last day of the 31-day month is a Friday. The video uses a digital blackboard for calculations and includes on-screen text with questions and options.

Chapters

  1. 0:00 – 2:00 00:00-02:00

    The video opens with a title card for a calendar problem. The first question displayed is "What is 89 days from today?" with the hint that today is January 20, 2017, a Sunday. The instructor, Yash Jain, begins to solve the problem by stating the total number of days is 89. He starts the calculation by writing "89" on the digital blackboard and begins to divide it by 7 to find the number of weeks and remaining days. The on-screen text clearly shows the question and the hint, providing the necessary information for the calculation.

  2. 2:00 – 5:00 02:00-05:00

    The instructor continues solving the first problem. He completes the division, writing "89 = 12*7 + 5" on the blackboard, indicating 12 weeks and 5 extra days. He then explains that adding 5 days to a Sunday results in a Friday. He calculates the date by adding 5 days to January 20, which is January 25, and then adds the remaining 12 weeks (84 days) to reach April 19, 2017. The on-screen text shows the options, and the instructor's final answer is option (a) 19th April, Friday. The video then transitions to the next problem, which is about a 30-day month starting on a Saturday with specific holidays.

  3. 5:00 – 6:02 05:00-06:02

    The video presents the third problem: "The second day of a month is Sunday. What will be the last day of the next month which has 31 days?" The instructor explains that if the second day is Sunday, the first day must be Saturday. He then calculates the last day of the 31-day month by counting forward from the first day. He writes "31" on the board and calculates 31 = 4*7 + 3, meaning 4 weeks and 3 extra days. Starting from Saturday, he adds 3 days to get Friday. The on-screen text shows the options, and the instructor concludes the answer is Friday, which is option (a). The video ends with a "THANKS FOR WATCHING" screen.

The video provides a structured, step-by-step approach to solving three distinct calendar-based aptitude problems. It begins with a straightforward date calculation, where the instructor uses division to find the number of weeks and extra days, then applies this to determine the day of the week and the final date. The second problem introduces the concept of counting working days by first identifying all holidays (Sundays and specific Saturdays) and subtracting them from the total days in the month. The final problem requires logical deduction to find the starting day of a month based on a given day, followed by a similar calculation to find the last day of a subsequent month. The consistent use of a digital blackboard for calculations and clear on-screen text for questions and options makes the teaching method effective and easy to follow.
