Takeaways

• 😀 UTBK 2025 students should understand that the General Reasoning section includes a quantitative reasoning subtest.
• 😀 Quantitative reasoning questions often involve formulas, P and Q relationships, and story problems that are slightly harder than general knowledge but easier than mathematics reasoning.
• 😀 Example problem: Calculating the remaining budget for product development when a portion has been used.
• 😀 To solve percentage problems, break down the total allocation and apply fractions to find the remaining amounts.
• 😀 Another example: Determining the total amount of rice bought by a trader using multiple statements to find X + Y.
• 😀 Understanding ratios is crucial, as shown in the bronze composition problem, where the weight of tin and copper must satisfy given fractions.
• 😀 Pattern recognition is necessary for sequences in story problems, such as sales data over several weeks to predict future values.
• 😀 Growth trends in plants can be calculated by identifying consistent patterns in sequential data.
• 😀 Target-setting problems require translating fractional differences into absolute quantities, like achieving a target production count.
• 😀 The video emphasizes practicing with tryouts, using video lessons, and joining online study groups or classes for UTBK preparation.

Q & A

What is the main focus of the UTBK preparation video?

The video primarily focuses on helping students prepare for the UTBK (Ujian Tulis Berbasis Komputer), especially the quantitative reasoning section, by providing problem-solving strategies and example questions.

What kind of questions are included in the quantitative reasoning section of UTBK?

The questions in the quantitative reasoning section often involve the application of formulas, logical relationships between variables, and more complex story-based problems that test students' mathematical reasoning skills.

How does the video help students understand the quantitative reasoning problems?

The video walks students through model questions, explaining the step-by-step thought process for solving them. It includes explanations for different question types and strategies for finding solutions efficiently.

In the first problem example, how is the budget for the two projects allocated?

The budget is split into 60% for product development and 40% for marketing. The problem then asks for the remaining budget for product development after a certain portion is used.

What was the correct answer for the remaining budget for product development in the first example?

The remaining budget for product development, after 1/4 of the budget has been used, is 45%. This is calculated using a step-by-step process involving basic percentage calculations.

What is the reasoning behind using the statement about the price and quantity of rice in problem 2?

The second problem provides multiple statements, and the goal is to determine which ones help calculate the total quantity of rice purchased. The necessary statements involve the price per kilogram and the relationship between the quantities of two types of rice (X and Y).

In problem 2, how do you calculate the amount of rice type X and Y purchased?

By using the fourth statement, we calculate the amount of rice X bought by dividing the total spent (600,000 IDR) by the price per kilogram (12,000 IDR). Then, using the third statement, we find that twice the amount of rice Y was purchased compared to X.

How does the third problem about bronze alloy composition work?

The third problem involves calculating how much copper is needed for a given amount of tin, based on the specified composition ratios. The key is converting all quantities into consistent units and applying the proportional relationships between the metals.

What is the formula used to solve the bronze alloy problem?

The formula involves setting up a proportion where the ratio of tin to copper is 3/5, and solving for the required copper given the amount of tin (1.8 kg), which results in 7,200 grams of copper.

How are the plant growth problems in the video solved?

The plant growth problems are solved by identifying the growth patterns for trees and shrubs over a series of years, using arithmetic progression. The total number of plants in the future year is calculated by applying the known pattern of growth to predict the future totals.

How is the problem about calculating the total plants after 5 years solved?

This problem is solved by observing the growth patterns of trees and shrubs, calculating the growth difference for each year, and then applying this pattern to predict the total number of plants that will be present after the fifth year.

What strategy is recommended for preparing for the UTBK based on the video?

The video recommends frequent practice through tryouts, reviewing a variety of problem types, and using quality study materials. It emphasizes practicing under timed conditions and utilizing study groups for support.
