High-Yield Reasoning Formulas & Shortcut Rules

TopicStandard Shortcut / FormulaApplication & Example
Angle between Clock Hands$$\theta = \left| 30H – \frac{11}{2}M \right|$$Finding interior angle between hour and minute hands at $H$ hours and $M$ minutes.
Total Persons in a Row (Ranking)$$\text{Total} = (\text{Rank from Left} + \text{Rank from Right}) – 1$$Calculating total candidates in a linear arrangement when one person’s both ends are known.
Opposite Faces on Standard Dice$$\text{Sum of opposite faces} = 7$$$1 \leftrightarrow 6$, $2 \leftrightarrow 5$, $3 \leftrightarrow 4$ in standard numerical dice.
Mirror Time Shortcut$$\text{Mirror Time} = 11:60 – \text{Actual Time}$$ (or $23:60$)Finding reflection clock time directly without drawing clocks.
Number of Triangles in a Divided Square$$\text{Total Triangles} = 2 \times N$$Where $N$ is the number of small internal numbered blocks inside the crossed square.

High-Yield Practice Questions on Reasoning

Apni preparation evaluate karne ke liye ye 5 selected standard exam questions solve karein:

Q1. [Clock] What is the angle between the hour hand and the minute hand of a clock at 4:20?

Check Answer

Answer: 10°.
Solution: Formula: $\theta = |30H – (11/2)M| = |30(4) – (11/2)(20)| = |120 – 110| = 10^\circ$.

Q2. [Syllogism] Statements: All cups are books. All books are shirts. Conclusions: (I) Some shirts are cups. (II) All cups are shirts.

Check Answer

Answer: Both Conclusion I and II follow.
Solution: Since Cup $\subset$ Book $\subset$ Shirt, all cups are definitely shirts, and hence some shirts are definitely cups.

Q3. [Blood Relation] Pointing to a man, a woman said, “His mother is the only daughter of my mother.” How is the woman related to the man?

Check Answer

Answer: Mother.
Solution: “Only daughter of my mother” means the woman herself. Thus, the woman is the mother of the man.

Q4. [Direction] A boy walks 12 meters East, turns right and walks 5 meters. What is his shortest distance from the starting point?

Check Answer

Answer: 13 meters.
Solution: By Pythagoras theorem: $\text{Shortest distance} = \sqrt{12^2 + 5^2} = \sqrt{144 + 25} = \sqrt{169} = 13\text{ m}$.

Q5. [Number Series] Find the missing number in the series: 2, 6, 12, 20, 30, 42, ?

Check Answer

Answer: 56.
Solution: The differences between terms are consecutive even numbers: $+4, +6, +8, +10, +12$. Thus, $42 + 14 = 56$ (or $n^2 + n$: $1^2+1, 2^2+2, \dots, 7^2+7 = 56$).
