Question:
12 times the middle of three consecutive even numbers is 152 more than 8 times the smallest of the three numbers. What is the middle number?
A34
B35
C33
D36
Answer:
A. 34
Explanation:
This is the general solution. Let the numbers be n-2, n and n +2. We are given 12 x n = 152 + 8 x (n - 2). 12 n = 152 + 8 n - 8 x 2. 12n - 8n = 152 - 16 = 136 4n = 136 n = 34
