TIPS MENGERJAKAN SOAL PM SNBT 2023

Summary

In this educational video, the host discusses changes to the 2023 SNBT exam, explaining the structure and focus of the tests, including the addition of a literacy section. The video covers various question types, with particular emphasis on mathematics reasoning. Through example problems, the host demonstrates how to approach them, focusing on key concepts and strategies to solve them effectively. The explanations include step-by-step solutions, helping viewers understand the logic behind each answer, making it an informative guide for those preparing for the SNBT exam.

Takeaways

• 😀 The 2023 SNBT exam follows the 2020 rules, meaning no TKA (IPA/IPS) exams, only the TPS (Test of Scholastic Potential) and a new literacy test.
• 😀 The SNBT now includes a total of 7 sub-tests, split into 4 TPS sections and 3 literacy sections (Bahasa Indonesia, English, and Mathematical Reasoning).
• 😀 Mathematical Reasoning tests focus more on problem-solving and analysis, differing from previous tests like PK (Quantitative Knowledge), which were more calculation-based.
• 😀 The first example problem explained how to calculate the revenue of a producer by incorporating price reductions and the number of items sold.
• 😀 Price reductions lead to a higher quantity sold, with each Rp200 reduction resulting in 50,000 more masks sold.
• 😀 The formula for calculating the producer's revenue after price reductions involves adjusting both the price and the quantity sold based on the number of reductions (X).
• 😀 In the second example, the problem calculates the percentage increase in revenue when the price of a mask decreases from Rp5000 to Rp4600.
• 😀 To solve the second problem, first calculate the initial revenue and then compare it to the new revenue after the price change, using the percentage formula.
• 😀 The third problem discusses the minimum amount of money that cannot be achieved in an envelope with 3 banknotes, ranging from Rp1000, Rp10,000, and Rp20,000.
• 😀 The smallest impossible total is Rp4000, as it’s not possible to combine any denominations of Rp1000, Rp5000, Rp10000, and Rp20000 to reach exactly Rp4000.
• 😀 The fourth problem deals with a legislative campaign's visiting schedule across 5 districts, where certain rules on order and dependencies between districts must be followed.

Q & A

What significant change occurred in the 2023 exam rules compared to previous years?

In 2023, the exam reverted to the 2020 regulations, where there is no longer a TKA (Test of Knowledge of Academic Subjects) for both IPS and IPA. Instead, the test only includes TPS (Test of Scholastic Potential) and an additional literacy test.

What are the components of the TPS in the 2023 exam?

The TPS consists of four components: general reasoning ability, general knowledge and understanding, reading comprehension, and quantitative knowledge (PK).

How does the literacy test in the 2023 exam differ from previous years?

The 2023 exam introduced a literacy test, which is divided into three parts: literacy in Bahasa Indonesia, literacy in English, and mathematical reasoning. This was not part of the previous year's exams.

What is the key difference between quantitative knowledge (PK) and mathematical reasoning in the 2023 exam?

Quantitative knowledge (PK) focuses on solving numerical problems, while mathematical reasoning involves analyzing word problems, determining what is known and what is being asked, and applying appropriate concepts or formulas.

How is the revenue model calculated for a mask producer who adjusts prices based on sales volume?

Revenue is calculated by multiplying the selling price of the mask by the quantity sold. When the price is reduced by Rp200, the producer can sell 50,000 more masks. The formula involves adjusting the price and quantity based on the number of price reductions.

How do you calculate the percentage increase in revenue when the price of a mask is reduced from Rp5000 to Rp4600?

To calculate the percentage increase in revenue, first find the revenue before and after the price change. Then, subtract the initial revenue from the new revenue, divide by the initial revenue, and multiply by 100 to get the percentage increase.

What is the smallest amount of money that is not possible to have in an envelope containing money and notes?

The smallest amount of money that cannot be in an envelope, based on the given conditions, is Rp4000. This is because it is impossible to combine the available denominations of Rp1000, Rp5000, Rp10000, and Rp20000 to make exactly Rp4000.

In the scenario with donations, how do you determine the smallest possible amount of money that can be in an envelope?

To determine the smallest possible amount, you start by considering all possible combinations of the notes (Rp1000, Rp10000, Rp20000) and the potential for some envelopes to contain only notes. The minimum amount that is not possible is Rp4000.

In a legislative campaign scenario, what determines the possible sequence of visits to the five districts (J, K, L, M, N)?

The visits must follow specific rules: the legislator can visit M only after visiting L and N, and cannot visit N before J. Based on these conditions, the sequence of visits must respect these constraints, and two districts must be visited after N, with L and M being the options.

What strategy should be used during a timed exam to maximize efficiency when solving questions?

To maximize efficiency, focus on identifying key information in each question right away and solve it without reading everything in full first. This approach helps save time, especially when answering complex word problems or sequences.
