Question
The average of 5 quantities is 6.The average of 3 of them is 4.What is the average of remaining 2 numbers?91089.
Solution
The problem states that the average of 5 quantities is 6. This means that the total sum of these 5 quantities is 5 * 6 = 30.
It also states that the average of 3 of these quantities is 4. This means that the total sum of these 3 quantities is 3 * 4 = 12.
To find the total sum of the remaining 2 quantities, we subtract the sum of the 3 quantities from the total sum of all 5 quantities. So, 30 - 12 = 18.
Finally, to find the average of these 2 quantities, we divide their total sum by the number of quantities. So, 18 / 2 = 9.
Therefore, the average of the remaining 2 numbers is 9.
