Quantity-Unit Analogy
Quantity-Unit Analogy problems involve pairs where one word represents a measurable quantity and the other represents its unit of measurement (e.g., Length : Meter). You must identify the quantity-unit relationship in the first pair and apply it to complete the second pair.

Introduction to Quantity-Unit Analogy
Quantity-Unit Analogy problems involve pairs where one word represents a measurable quantity and the other represents its unit of measurement (e.g., Length : Meter). You must identify the quantity-unit relationship in the first pair and apply it to complete the second pair.
Prerequisites
How to Solve Quantity-Unit Analogy Problems
Step 1: Identify the relationship between the first pair of words (A : B)
Step 2: Determine if A is the quantity and B is its unit, or vice versa
Step 3: Note the direction (quantity→unit or unit→quantity)
Step 4: Look at the third word (C) and find a word (D) that has the same measurement relationship with C
Step 5: Maintain the same direction of relationship
Step 6: Eliminate options that don't fit the quantity-unit relationship
Step 7: Choose the option that best maintains the quantity-unit relationship
Example Problem
Example: Length : Meter :: Weight : ? Solution: Step 1: Length is measured in Meter (quantity → unit) Step 2: The relationship is 'quantity to its unit' Step 3: We need the unit of Weight Step 4: Options: (a) Second (b) Kilogram (c) Liter (d) Celsius Step 5: Weight is measured in Kilogram Step 6: Length : Meter :: Weight : Kilogram Answer: Kilogram
Pro Tips & Tricks
- Learn common quantity-unit pairs: Length-Meter, Weight-Kilogram, Time-Second, Temperature-Celsius, Volume-Liter, Energy-Joule, Power-Watt, Frequency-Hertz, Pressure-Pascal, Speed-km/h, Data-Byte
- Understand that some quantities have multiple units (Length: meter, foot, inch, mile)
- Consider the standard or most commonly used unit in the context
- Remember that some units are named after scientists (Newton, Pascal, Watt, Joule)
- Be aware of derived units (Speed = km/h, Density = kg/m³)
- Watch for units that are used for multiple quantities (Second for time and angle)
