- Khel Ratna Award
- India's highest sporting honour, renamed after hockey legend Major Dhyan Chand; it is presented annually for outstanding sporting performance.
- Reverse alphabet position
- Value obtained by subtracting a letter's forward position from 27; for example E has forward 5 and reverse 22.
- Clock hand angle formula
- Angle between hour and minute hands equals the absolute value of 30H minus 5.5M, where H is hour and M is minutes.
- Syllogism validity rule
- A conclusion follows only if it is true in every possible Venn diagram consistent with the premises; 'some' never implies 'all'.
- Blood relation diagram
- Family-tree convention: vertical links show parent-child, horizontal links show spouse, and gender is marked with distinct symbols.
- Successive percentage change
- Two successive changes of a percent and b percent give a net change of a plus b plus ab divided by 100.
- Alligation rule
- Ratio of two quantities mixed to reach a mean price equals mean minus cheaper, divided by dearer minus mean.
- Combined work formula
- If A alone takes x days and B takes y days, together they finish the work in xy divided by x plus y days.
- km/h to m/s
- Multiply a speed in kilometres per hour by 5/18 to convert it to metres per second; reverse by multiplying by 18/5.
- दीर्घ संधि
- जब अ, आ, इ, ई, उ, ऊ या ऋ के बाद समान स्वर आए तो दोनों मिलकर दीर्घ स्वर बनते हैं, जैसे विद्या + आलय = विद्यालय।
- बहुव्रीहि समास
- वह समास जिसमें कोई भी पद प्रधान न होकर समस्त पद किसी तीसरे अर्थ की ओर संकेत करता है, जैसे दशानन = दस सिर वाला।
- तत्सम और तद्भव

- Ohm's law
- Current through a conductor is directly proportional to voltage across it at constant temperature; V equals IR.
- Kirchhoff's current law
- The algebraic sum of currents entering and leaving a node is zero, expressing conservation of charge at that junction.
- Transformer EMF equation
- Induced EMF per winding equals 4.44 times frequency times turns times peak flux, with f in hertz and flux in webers.
- Back EMF of DC motor
- Counter EMF equals supply voltage minus armature current times armature resistance; it limits armature current at running speed.
- Young's modulus
- Ratio of tensile stress to longitudinal strain within the elastic limit; it measures a material's stiffness.
- Reynolds number
- Dimensionless ratio of inertial to viscous forces, calculated as density times velocity times diameter divided by dynamic viscosity.
- First law of thermodynamics
- Heat supplied to a system equals the increase in internal energy plus the work done by the system.
- Star-delta relation
- In a balanced star connection line voltage is root three times phase voltage; in delta, line current is root three times phase current.
- Directive Principles
- Guidelines in Part IV, Articles 36 to 51, aimed at state policy; they are not enforceable in courts.
- Odd-one-out strategy
- Classify the relation among the given items first, such as part-whole or worker-tool, then reject the option that breaks it.
