Question
Average of 3rd and 4th number in 5 consecutive numbers is 10.
What is the sum of these 5 numbers?
47.5
10.25
23.5
Solution
The average of the 3rd and 4th numbers in a set of 5 consecutive numbers is 10. This means that the 3rd and 4th numbers are 9 and 11 respectively (since they are consecutive and their average is 10).
In a set of 5 consecutive numbers, if the 3rd number is 9, then the 1st and 2nd numbers are 7 and 8, and the 5th number is 12.
So, the sum of these 5 numbers is 7 + 8 + 9 + 11 + 12 = 47.
