The average of 5 quantities is 6. The average of 3 of them is 4. What is the average of remaining 2 numbers?
- 2
- 5
- 6
- 9
Explanation
- Average of 5 quantities = 6
So, total sum of 5 = 5 × 6 = 30
- Average of 3 quantities = 4
So, total sum of 3 = 3 × 4 = 12
- Sum of remaining 2 = 30 − 12 = 18
- Average of remaining 2 = 18 ÷ 2 = 9
