This cheat sheet provides a high-level overview and essential preparation strategies for the General Test section of the CUET examination. It covers key concepts, important formulas, common pitfalls, and quick revision points to help aspirants maximize their scores in this diverse and crucial component.
Key Concepts
The CUET General Test assesses a candidate's aptitude across various domains, including numerical ability, logical reasoning, general knowledge, and current affairs. Success in this section requires not only foundational knowledge but also quick problem-solving skills and an ability to analyze information effectively.
Numerical Ability
This section tests basic mathematical concepts up to Class 8/10 level. It includes topics like arithmetic, number systems, percentage, profit and loss, time and work, speed-distance-time, simple and compound interest, averages, ratio and proportion, and basic mensuration. Data Interpretation (DI) based on charts, graphs, and tables is also a crucial part. Focus is on speed and accuracy in calculations.
Logical and Analytical Reasoning
This part evaluates a candidate's ability to interpret patterns, draw logical conclusions, and solve problems using analytical thinking. Topics include series (number, alphabet, alphanumeric), analogies, classification, coding-decoding, blood relations, directions, Venn diagrams, syllogisms, sitting arrangements, puzzles, statement & assumptions, statement & conclusions. Non-verbal reasoning, involving figures, is also common.
General Knowledge
This broad section covers static general knowledge across various disciplines. It includes Indian history (ancient, medieval, modern), Indian geography, Indian polity (constitution, government structure), economy (basic concepts), science (physics, chemistry, biology - basics), famous personalities, awards, books and authors, important dates, and international organizations.
Current Affairs
This segment assesses awareness of recent events, national and international news, government schemes, sports, science and technology developments, and significant appointments from the last 6-12 months. Regular reading of newspapers and magazines is essential for this part.
Formulas & Results
Numerical Ability Essential Formulas
- Percentage Change: $$ \text{Percentage Change} = \frac{\text{Change}}{\text{Original Value}} \times 100 $$
- Profit & Loss: $$ \text{Profit %} = \frac{\text{Profit}}{\text{C.P.}} \times 100 , ; , \text{Loss %} = \frac{\text{Loss}}{\text{C.P.}} \times 100 $$
- Simple Interest (SI): $$ \text{SI} = \frac{P \times R \times T}{100} $$ Where $P$ = Principal, $R$ = Rate, $T$ = Time.
- Compound Interest (CI): $$ A = P \left(1 + \frac{R}{100}\right)^T , ; , \text{CI} = A - P $$ Where $A$ = Amount.
- Speed, Distance, Time: $$ \text{Distance} = \text{Speed} \times \text{Time} $$ $$ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} $$
- Work & Time (Inverse Proportion): If A takes $x$ days to do a work, A's 1-day work is $1/x$. If A and B work together, their combined 1-day work is $(1/x + 1/y)$.
- Average: $$ \text{Average} = \frac{\text{Sum of Observations}}{\text{Number of Observations}} $$
- Ratio and Proportion: If $a:b = c:d$, then $ad = bc$.
Logical Reasoning General Patterns
- Number Series: Common patterns include arithmetic progression (AP), geometric progression (GP), difference series, sum/product series, perfect squares/cubes, alternate series.
- Alphabet Series: Position of letters (A=1, Z=26), skipped letters, Vowel/Consonant patterns.
- Coding-Decoding: Letter shifting (e.g., +1, -2), reversal, common pattern substitution.
- Blood Relations: Diagrams are most effective. Remember basic relations like 'My mother's father's only daughter' is 'mother'.
- Direction Sense: Always start from a reference point and use diagrams. East, West, North, South, and their intermediates.
Worked Examples
Example 1: Numerical Ability
Q: A shopkeeper sells an item at a profit of 20%. If he had bought it for 10% less and sold it for ₹18 less, he would have gained 30%. Find the original cost price of the item.
Solution: Let the original Cost Price (C.P.) be $C$. Original Selling Price (S.P.) = $C + 0.20C = 1.20C$.
New C.P. = $C - 0.10C = 0.90C$. New Profit = 30%. New S.P. = New C.P. $+ 0.30 \times \text{New C.P.} = 0.90C + 0.30(0.90C) = 0.90C + 0.27C = 1.17C$.
According to the problem, the new S.P. is ₹18 less than the original S.P. Original S.P. $-$ New S.P. $= 18$ $1.20C - 1.17C = 18$ $0.03C = 18$ $C = \frac{18}{0.03} = \frac{18 \times 100}{3} = 6 \times 100 = 600$.
The original cost price of the item is ₹600.
Example 2: Logical Reasoning
Q: In a certain code language, "APPLE" is written as "ERPMJ". How is "ORANGE" written in that code language?
Solution: Let's analyze the pattern for "APPLE" to "ERPMJ": A (+4) -> E P (+2) -> R P (-3) -> M L (-2) -> J (L is 12, J is 10) E (+5) -> J (E is 5, J is 10)
The pattern is +4, +2, -3, -2, +5 (alternating shifts). This seems a bit complex. Let's re-evaluate.
Another common pattern is letter positions or simple shifts. A (1) -> E (5) = +4 P (16) -> R (18) = +2 P (16) -> M (13) = -3 L (12) -> J (10) = -2 E (5) -> J (10) = +5
The pattern for the shifts is +4, +2, -3, -2, +5. This is unusual. Let's look for a simpler pattern. Could it be related to position or a different kind of shift?
Let's re-examine if there's a simpler, more consistent shift that occurs often in entrance exams. A $\xrightarrow{+4}$ E P $\xrightarrow{+2}$ R P $\xrightarrow{-3}$ M L $\xrightarrow{-2}$ J E $\xrightarrow{+5}$ J
This is indeed a complex mixed pattern. Assuming this is the intended one, let's apply it to "ORANGE": O $\xrightarrow{+4}$ S R $\xrightarrow{+2}$ T A $\xrightarrow{-3}$ X (A is 1, so -3 makes it 24, which is X) N $\xrightarrow{-2}$ L G $\xrightarrow{+5}$ L E $\xrightarrow{+0}$ E (Assuming the pattern ends after 5 shifts, or a 6th letter may get +0 or reset)
This mixed pattern (+4, +2, -3, -2, +5, +0...) is highly improbable for a typical exam question. Let's assume there was a simpler pattern or a typo in the question. If the shifts were, for example, just increments: A (+1) B P (+1) Q P (+1) Q L (+1) M E (+1) F -> BQQMF. This is not ERPMJ.
Let's assume the question meant a different set of shifts, or a consistent shift throughout. If it was a consistent shift across all letters, e.g., +2: APPLE $\rightarrow$ CRRNG. Not ERPMJ.
Let's reconsider the observed shifts: +4, +2, -3, -2, +5. This is a very specific sequence. If we are forced to use it, and "ORANGE" has 6 letters, we need to apply the pattern for all 6. Assuming the pattern repeats or continues: O (+4) $\rightarrow$ S R (+2) $\rightarrow$ T A (-3) $\rightarrow$ X N (-2) $\rightarrow$ L G (+5) $\rightarrow$ L E (If pattern cycles, next is +4) $\rightarrow$ I
This gives "STXL LI". This is a tricky one due to the irregular pattern. In CUET, such highly irregular patterns are rare; usually, there's a simpler logical progression. However, if this pattern is given, we must follow it. Let's assume the pattern given was exactly as observed for 5 letters, and "ORANGE" has 6. This typically means the pattern might repeat for the 6th, or the question only applies to 5-letter words.
Let's re-evaluate "APPLE" (A=1, P=16, P=16, L=12, E=5) to "ERPMJ" (E=5, R=18, M=13, J=10, J=10). Differences: +4, +2, -3, -2, +5. This is the correct derivation.
Now apply this to "ORANGE": O (15) + 4 = 19 (S) R (18) + 2 = 20 (T) A (1) - 3 = -2 (which is 26 - 2 = 24, so X) N (14) - 2 = 12 (L) G (7) + 5 = 12 (L) E (5) - The pattern sequence has 5 distinct operations. For the 6th letter, if the pattern repeats, it would be +4. So E+4 = I. Thus, "ORANGE" is coded as "STXLLI". This type of irregular pattern is challenging. Always trace step-by-step.
Example 3: General Knowledge
Q: Which of the following is the highest peak in the Aravalli Range? (A) Guru Shikhar (B) Dodabetta (C) Anamudi (D) Kanchenjunga
Solution: The Aravalli Range is one of the oldest fold mountain ranges in the world, located in western India. Its highest peak is Guru Shikhar, situated in the state of Rajasthan, near Mount Abu. Dodabetta is the highest peak in the Nilgiri Hills. Anamudi is the highest peak in the Western Ghats (Kerala). Kanchenjunga is the third highest mountain in the world and part of the Himalayas.
Therefore, the correct answer is (A) Guru Shikhar.
Common Mistakes
- Rushing through calculations: Leading to arithmetic errors in Numerical Ability. Always double-check.
- Misinterpreting instructions: Not reading questions carefully, especially in Logical Reasoning (e.g., "not included," "except").
- Lack of time management: Spending too much time on a single difficult question, neglecting easier ones. The General Test often has more questions for less time per question.
- Guessing randomly: Negative marking can penalize random guesses. If unsure, prioritize questions where you can eliminate at least two options.
- Neglecting current affairs: Many students focus only on static GK. Current affairs are equally important and dynamic, requiring regular updates.
- Assuming patterns: In Logical Reasoning, don't assume a pattern; verify it rigorously with all given examples.
- Memorizing vs. Understanding: For GK, rote learning without understanding context makes recall difficult. For Numerical Ability, understanding concepts is better than just memorizing formulas.
- Not developing a strategy for DI: For Data Interpretation, quickly analyzing the type of chart/graph and what it represents before diving into calculations is crucial.
