Re: a, b, c, d, and e are positive integers satisfying the following. What is the value of a + b + c + d + e?
There is no way to solve this without knowing more information, I think you are missing some of the necessary criteria on a, b, c, d, and e.

Problem Solving
If the average (arithmetic mean) of x, y and 15 is 9, and the average of x, 2y and 2 is 7, then y =?
If the average (arithmetic mean) of x, y and 15 is 9, and the average of x, 2y and 2 is 7, then y =
A 5
B 6
C 7
D 8
E 9
To solve this we know that:
x+y+15 =27
hence, x+y=12
x+2y+2=12
hence, x+2y=19
Subtracting the two we get y=7 so C is correct

Problem Solving
If k is an integer and k = 462/n, then which of the following could be the value of n?
If k is an integer and k = 462/n, then which of the following could be the value of n?
A 4
B 5
C 9
D 13
E 22
To solve, we need to find all the factors of 462, which are 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462.
Since 22 is a factor then it is our answer, which is E.

If k is an odd integer, which of the following must be an even integer?
If k is an odd integer, which of the following must be an even integer?
A k2 − 4
B 3k + 2
