Verified Answer
For all positive integers x,when x is even and when x is odd. What is ...
Steps 1 & 2: Understand Question and Draw Inferences
Given:
  • Integer x > 0
Step 3: Analyze Statement 1 independently
(1) The highest power of 2 that divides &(4x) completely is 36
  • This means, &(4x) contains 236 but not any higher power of 2
  • 4x is definitely an even integer.
  • In this case, the power of 2 will only come from the term 24x+2
  • Since the highest power of 2 in &(4x) is 36, we can write:
    • 4x + 2 = 36
  • That is, 4x = 34
  • This doesn’t give an integral value of x. So, this case is rejected.
  • Case 2: x is even
    • In this case, x contains at least 21 but may also contain higher powers of 2.
    • So, we will have to consider these possibilities:
  • So, the only possible value of x = 22 = 4
Thus, Statement 1 is sufficient to determine a unique value of x.
Step 4: Analyze Statement 2 independently
(2) The highest power of 2 that divides (&4)*x completely is 8
  • Statement 2 tells us that the highest power of 2 that divides 26x is 8
    • 26 is a constant. The power of 2 in this number is 6
  • So, from Statement 2, we infer that the highest power of 2 contained in x is 2
    • So, x is divisible by 22 (that is, 4) but not be 23, 24 etc.
    • Thus, x must be of the form 4 * odd number
  • So, x = 4(2k+1) where k is a positive integer
  • Values such as 4*1, 4*3, 4*5 etc. will all satisfy Statement 2
Thus, Statement 2 is not sufficient to determine a unique value of x.
Step 5: Analyze Both Statements Together (if needed)
Since we’ve already arrived at a unique answer in Step 3, this step is not required
Answer: Option A
