FAQs on Tricks to solve Problems: Average Based Equations Video Lecture - Quantitative Techniques for CLAT

1. What is the formula to calculate the average of a set of numbers?
Ans. The formula to calculate the average of a set of numbers is to sum all the numbers and divide the sum by the total count of numbers in the set.
2. How can I find the missing number in a set of numbers to maintain the given average?
Ans. To find the missing number in a set of numbers and maintain the given average, multiply the average by the total count of numbers plus one, and then subtract the sum of the given numbers from this value. The result will be the missing number.
3. How can I calculate the average of two sets of numbers with different counts?
Ans. To calculate the average of two sets of numbers with different counts, multiply the average of the first set by the count of numbers in the first set, and multiply the average of the second set by the count of numbers in the second set. Then, add these two values together and divide the sum by the total count of numbers in both sets combined.
4. Can the average of a set of numbers be greater than the largest number in the set?
Ans. No, the average of a set of numbers cannot be greater than the largest number in the set. The average represents the central tendency of the set, and it is calculated by dividing the sum of all the numbers by the count of numbers. Since the average is influenced by all the numbers in the set, it cannot exceed the largest number.
5. How does adding an outlier affect the average of a set of numbers?
Ans. Adding an outlier, a significantly higher or lower value, can greatly affect the average of a set of numbers. The outlier pulls the average towards itself, causing a distortion in the overall representation of the data. Therefore, it is important to be cautious when including outliers in calculations involving averages.
