10 Important Average Questions for RRB Clerk 2026 with Answers: Take Quiz
The following average questions for RRB Clerk 2026 cover different patterns commonly practised in banking examinations. Try solving each question independently before checking its answer and explanation.
Q1. Average of a Group
The average weight of 5 men in a boat is 65 kg. When the weight of the boat is included, the average increases by 2 kg. Find the weight of the boat.
Total weight of 5 men = 5 × 65 = 325 kg.
New average = 65 + 2 = 67 kg.
Total weight including the boat = 6 × 67 = 402 kg.
Weight of the boat = 402 − 325 = 77 kg.
Q2. Average of Students
The average weight of 24 students is 45 kg. When the teacher joins them, the average increases by 1 kg. Find the teacher’s weight.
Original total = 24 × 45 = 1080 kg.
New average = 45 + 1 = 46 kg.
New total = 25 × 46 = 1150 kg.
Teacher’s weight = 1150 − 1080 = 70 kg.
Q3. Consecutive Even Numbers
The average of five consecutive even numbers is 38. Find the product of the smallest and largest numbers.
The middle number is equal to the average.
The numbers are 34, 36, 38, 40 and 42.
Product of the smallest and largest numbers = 34 × 42 = 1428.
Q4. Replacement of Members
The average age of 10 men increases by 2 years when two men aged 20 and 24 years are replaced by two women. Find the average age of the two women.
Increase in total age = 10 × 2 = 20 years.
Original ages of the replaced men = 20 + 24 = 44 years.
Total age of the two women = 44 + 20 = 64 years.
Average age = 64 ÷ 2 = 32 years.
Q5. Missing Number
The average of six numbers is 25. Five numbers are 20, 22, 24, 26 and 28. Find the sixth number.
Total of six numbers = 6 × 25 = 150.
Sum of five given numbers = 20 + 22 + 24 + 26 + 28 = 120.
Sixth number = 150 − 120 = 30.
Q6. Average Marks
A student scores 65, 70, 75, 80 and 85 marks in five subjects. Find the average marks.
Total marks = 65 + 70 + 75 + 80 + 85 = 375.
Average marks = 375 ÷ 5 = 75.
Q7. Average Age
The average age of 8 people is 30 years. If one person aged 23 years leaves, find the new average.
Original total age = 8 × 30 = 240 years.
Remaining total age = 240 − 23 = 217 years.
New average = 217 ÷ 7 = 31 years.
Q8. Average Runs
A batsman scores 45, 60, 75, 80 and 90 runs in five matches. Find his average score.
Total runs = 45 + 60 + 75 + 80 + 90 = 350.
Average score = 350 ÷ 5 = 70 runs.
Q9. Average of Numbers
The average of 12 numbers is 18. If each number is increased by 4, find the new average.
When every number increases by 4, the average also increases by 4.
New average = 18 + 4 = 22.
Q10. Average Weight
The average weight of 15 people is 60 kg. If a person weighing 75 kg joins the group, find the new average.
Original total weight = 15 × 60 = 900 kg.
New total weight = 900 + 75 = 975 kg.
New average = 975 ÷ 16 = 60.94 kg approximately.

Solve More QuestionsImportant Types of Average Questions for RRB Clerk 2026
Understanding the different types of average questions for bank exams helps candidates identify the correct method quickly. Most practice questions revolve around changes in total values, missing observations and group averages.
| Question Type | What to Practise |
| Basic Average | Average of given numbers |
| Missing Number | Finding an unknown observation |
| Age-Based | Average age of individuals |
| Replacement | Change in average after replacement |
| Consecutive Numbers | Average of consecutive odd or even numbers |
| Weight-Based | Average weight of a group |
| Sports-Based | Average runs or scores |
| Combined Average | Average of two or more groups |
Important Average Formula and Shortcuts for RRB Clerk
The average formula is the foundation of average questions for RRB Clerk 2026. Candidates should memorise the following formulas before practising advanced questions.
| Concept | Formula |
| Average | Sum of observations / Number of observations |
| Total Sum | Average x Number of observations |
| New Average | New Total / New Number |
| Addition | New Average = Old Average + Increase in Total / New Count |
| Removal | New Average = Old Average – Removed Value Difference / Remaining Count |
| Consecutive Numbers | Average = Middle Number |
Deviation Method
The deviation method helps reduce lengthy calculations when numbers are close to each other. Assume a convenient average and calculate the difference between each observation and the assumed value.
For example, the average of 48, 52, 54 and 46 can be calculated using 50 as the assumed average.
Deviations are -2, +2, +4 and -4.
Net deviation = 0.
Therefore, the average is 50.
Replacement Shortcut
When one person replaces another, calculate the change in the total rather than finding the complete sum again.
For example, if a person aged 25 is replaced by someone aged 35 in a group of 10, the total increases by 10 years.
Increase in average = 10 / 10 = 1 year.
How to Prepare Average Questions for RRB Clerk 2026
