Question

State if the given statement is True or False.

If c and d are odd integers, then $c-3d$ is even.

• A. True
• B. False

Answer 1

The correct option is A True

given that

$c,d$ are odd integers

$odd+odd=Even$

$odd-odd=Even$

$odd\times odd=Odd$

Now

$3d=Odd$

$c$ is also odd

$c-3d=Even$ using rule $odd-odd=Even$

So the statement is true
