If m And p are positive integers and ( m + p ) m is even , which of the following must be true ?
A
If m is odd , then p is odd
B
If m is odd , then o is even
C
If m is even, then p is even
D
If m is even, then p is odd
Correct Answer: If m is odd , then p is odd
m যদি বিজোড় হয় তখন p শুধুমাত্র জোড় হলেই ( m + p) m জোড় হবে। এটাই সঠিক।
