Answer 2

Answer:

1. 1

2. 0 and 5

Step-by-step explanation:

Any number which has multiple of 2 at one's place are divisible by 2.

multiple of 2 are - 2, 4, 6, 8.

Numbers ending with 0 are also divisible by two.

10, 20, 30, 40, 50, 60, etc., are all divisible by 2.

Therefore, any number which has 1 at one's place is NOT divisible by 2.

Correct option is 1.

any number which is ending with 5 or 0 is divisible by 5.

numbers like - 5, 10, 15, 20, 25, 30 and so on are all divisible by 5

numbers like 12, 16, 73, 84 91 are not divisible by 5.

so Correct answer is 0 and 5
