(a) 14

(b) 15

(c) 16

(d) 17Answer: (c) 16Solution: The total sum of the 5 numbers is

5×12=60.

Given that the sum of the first three numbers is 36 and the sum of the last three numbers is 48, the fourth number is calculated as follows:

48−36=12.

Therefore, the sum of the fourth and fifth numbers is

60−36=24.

Since the sum of the last three numbers is 48, and the sum of the first three numbers is 36, the difference between the sums of the last three numbers and the first three numbers equals the fourth number.

Therefore, the fourth number is 16. - The average of 10 numbers is 20. If the sum of the first five numbers is 80, what is the average of the last five numbers?

(b) 16

(c) 20

(d) 24Answer: (d) 24Solution: The total sum of the 10 numbers is

10×20=200.

Given the sum of the first five numbers is 80, the sum of the last five numbers is:

200−80=120

The average of the last five numbers is calculated as:

120÷5=24

Therefore, the average of the last five numbers is 24. - The average of a set of numbers is 30. If the sum of all the numbers is 360, how many numbers are in the set?

(a) 12

(b) 15

(d) 20

Answer: (a) 12

Solution: Given the average of the numbers is 30 and the sum of all the numbers is 360, we can find the number of values in the set by dividing the sum by the average:

360÷30=12

Therefore, there are 12 numbers in the set. - The average of 4 consecutive integers is 18.5. What is the largest integer in the set?
