Q & A

What is the topic of the video by Asmar Rahmad on the Goromet channel?

The video covers quantitative knowledge questions (Pengetahuan Kuantitatif) from the UTBK 2025, specifically discussing the first 5 questions of package 1.

How many types of questions are discussed in the video?

The video discusses multiple types of questions: short-answer questions and multiple-choice questions.

How is the first question involving 4 divided by 1/2 solved?

The division 4 ÷ 1/2 is converted to multiplication: 4 × 2 = 8. Then, since √t = 8, t is squared to get t = 64.

What method is used to find r in the second question about the function f(x) = x^2 - rx + 33?

The given point (17, f(17)) is substituted into the function. Then algebraic manipulation is performed to solve for r, yielding r = 10 according to the transcript.

In question 3, how are U and T determined from the set of numbers?

The numbers are first sorted from largest to smallest. U represents the third largest number, and T represents the eighth. Then the expression 2U - T is calculated.

How many total squares are identified in question 4, which involves a combination of small and large squares?

There are 12 squares in total: 8 small squares and 4 larger squares formed by combining smaller ones.

How is the value of [1 - [2]] calculated in question 5 using the piecewise function?

First, [2] is calculated using the formula for even positive numbers: (2^2 + 2)/2 = 3. Then 1 - [2] = -2. Since -2 is even and negative, the formula for even negative numbers is applied: 2(-2)^2 + 1 = 9.

What strategies does Asmar Rahmad suggest for solving these types of UTBK quantitative questions?

He emphasizes step-by-step substitution, careful calculation, identifying the type of number (odd, even, positive, negative), and logical organization of data such as sorting numbers or grouping squares.

Why is it important to distinguish between different types of numbers in question 5?

Because the piecewise function assigns different formulas depending on whether the number is odd, even positive, or even negative, which directly affects the calculation result.

What is the purpose of splitting the 20-question package into smaller parts in the video series?

The purpose is to make the material easier to digest and allow viewers to focus on a manageable number of questions at a time. In this part, only questions 1–5 are covered.
