If Ratio is 3:4 and Antecedent is 15, What is the Consequent?

How to Find the Consequent When Antecedent is Known – Solved Example

One of the most commonly tested questions in quantitative aptitude is based on ratios. Let’s solve a simple yet important example that often appears in exams.

🧮 Question:The ratio of two quantities is 3:4. If the antecedent is 15, what is the consequent?

📌 Concept Reminder:In a ratio a : b,

• a is the antecedent

• b is the consequent
