LATIHAN SOAL NUMERICAL - ABILITY TO LEARN (PSIKOTEST/VERIFIKASI ONLINE MAGANG BAKTI BCA)

Summary

In this video, the speaker shares a walkthrough of common numerical and logical reasoning questions similar to those found in the BCA internship psychotest and verification exam. Starting with simple number sequences and basic math patterns, the video gradually moves to more applied problems involving speed, distance, time, money calculations, and time zone differences. The presenter explains each solution step-by-step using practical shortcuts and easy-to-follow logic, helping viewers understand patterns rather than memorize formulas. The session is designed to make test preparation less intimidating and more approachable for candidates aiming to successfully join the BCA internship program.

• 😀 It also includes a scenario where a flight from London to New York takes off at 1:12 PM London time, and the viewers are guided on how to calculate the journey's length considering time zone differences.
• 😀 Lastly, a math problem involving distances traveled by a car at varying speeds is discussed, with a focus on how to calculate the average speed over different segments of a journey.

Q & A

What is the first numerical sequence presented in the video, and how is it solved?

The first numerical sequence is 2, 4, 6, 8, 10, 12. The pattern is that each number increases by 2. The next number in the sequence is 14, as 12 + 2 = 14.

How do you solve the problem about the car's constant speed?

The car's speed is 60 km/h. The distance traveled in 1.5 hours can be calculated by multiplying speed by time: 60 * 1.5 = 90 km.

What is the formula used for calculating speed, distance, and time?

The formula for speed is: Speed = Distance / Time. Rearranged for distance, it becomes: Distance = Speed * Time. For time, it is: Time = Distance / Speed.

What is the method to solve the sequence 1.08, 1.20, 1.40, 2.00, 1.44?

The sequence increases by 12 units each time, so after 1.44, the next number would be 1.44 + 12 = 1.56.

What distinguishes the odd number in the sequence 12, 10, 15?

The numbers 12 and 10 are even, while 15 is odd. Thus, 15 is the outlier in this sequence.

How do you calculate the remaining balance in the cash box after purchasing items?

The total spent on the pens is 2 * 1800 = 3600, and on the books, it is 2 * 5200 = 10400. The remaining balance is 52610 - 3600 - 10400 = 38610.

How do you determine the time difference between London, New York, and Los Angeles?

The time difference is calculated by subtracting the respective hours. If it’s 4:00 PM in London, subtract 5 hours for New York (11:00 AM), and then subtract 3 hours for Los Angeles (8:00 AM).

How do you calculate the time spent on a flight from London to New York, given the time zones?

If the flight departs London at 1:12 PM, the equivalent time in New York is 8:12 AM (5 hours behind). The flight lands at 1:18 PM New York time. Subtracting the departure time from the landing time (1:18 PM - 8:12 AM) gives the flight duration of 5 hours and 6 minutes.

How do you solve a problem where you need to calculate the next number in a sequence with many zeros?

In the sequence 15, 320, 3600, 120, the method involves identifying a common divisor. The numbers reduce by dividing by 5, so the next number after 120 is 24.

How do you solve the problem of determining the speed of a car in the last hour of a trip?

The car travels 150 km in total, with 120 km covered in the first 3 hours at a speed of 40 km/h. The remaining distance is 30 km. Since the time left is 1 hour, the speed during the last hour is 30 km/h.
