Given below are two statements:

Statement I : If a number is divisible by 4, it must be divisible by 2.
Statement II : If a number is divisible by 2, it must be divisible by 4.

In the light of the above statements,choose the Correct answer from the options given below:

  • A.Both Statement I and Statement II are true.
  • B.Both Statement I and Statement II are false.
  • C.Statement I is true but Statement II is false.
  • D.Statement I is false but Statement II is true.

Answer: C

Statement I is true but Statement II is false.

Statement I: every multiple of 4 is \(4k = 2(2k)\), so it is also a multiple of 2. True.

Statement II is the converse, and it fails: 2, 6 and 10 are divisible by 2 but not by 4. A rule of the form 'divisible by m implies divisible by n' holds only when n is a factor of m, so the step from 4 to 2 works but the step from 2 to 4 does not.

That rules out 'both true', 'both false' and the reversed option.
