📘 Average & Age Related Problems – CUET GT Notes Summary
Average and Age Related Problems are important topics in the Quantitative Aptitude section of the CUET General Test (GT). These concepts help in understanding how to find the central value of numbers and solve questions related to the ages of people in different time periods. 📊
🔹 Average (Mean) Concept
The average represents the central or typical value of a group of numbers. It is calculated by dividing the total sum of all values by the number of values. 📈
📌 Formula:
Average = (Sum of all observations) / (Number of observations)
💡 Example:
If the marks of five students are 60, 70, 80, 75, and 65, then:
Average = (60 + 70 + 80 + 75 + 65) / 5 = 70 📚
📍 Important Points:
- If the average increases, the total sum also increases. 📊
- If a new value is added, the average changes accordingly. ➕
- Average helps solve problems related to marks, salary, runs, and data sets. 📈
🔹 Age Related Problems 👨👩👧
Age problems involve finding the present, past, or future ages of people using equations and logical relationships.
📌 Basic Concept:
- Age increases by 1 year every year. ⏳
- If a person’s present age is x, then:
Age after n years = x + n
Age n years ago = x − n
💡 Example:
If Rahul’s present age is 20 years, then:
- Age after 5 years = 25 years
- Age 5 years ago = 15 years
🔹 CUET GT Preparation Tips 🎯
- Memorize the average formula and practice quick calculations.
- Use algebraic equations to solve age problems.
- Practice previous CUET quantitative aptitude questions.
- Focus on logical reasoning and shortcut techniques.
🚀 Mastering Average and Age Related Problems will help you solve many CUET GT quantitative aptitude questions quickly and accurately.
