Question

If two numbers, both of which are not divisible by 7, are added, then their sum is divisible by 7?

Answer 1

Answer:

Step-by-step explanation:

NOT TRUE.

2 and 3 are not divisible by 7 and so is 2 + 3 = 5.

Answer 2

Answer:

1 and 6 are the two numbers.

Step-by-step explanation:

Let us consider one number be 1 and the another number be 6. Both 1 and 6 are not divisible by 7, thus it fulfills the one given condition.

Now, if we add these numbers, then

$1+6=7$ which is divisible by 7.

Therefore, 1 and 6 are the two numbers which are not divisible by 7 but if they are added then their sum is divisible by 7.
