Answer:

i) Divisible, not divisible, divisible

ii) divisible, Divisible, divisible

iii) Divisible, Divisible, Not Divisible.

Step by step Explanation:

  • A number is divisible by 25 if the number ends with 00, 25, 50 or 75.

In the first 3 problems, (6125 and 39250) is divisible by 25 as it satisfies the condition.

  • A number is divisible by 6 if the number is divisible by both 2 and 3.
  1. Divisibility Rule of 2:

Should end with even number.

2. Divisibility Rule of 3:

If the sum of digits is divisible by 3.

In the three problems, all the three are divisible by 6 as it satisfies the condition.

  • A number is divisible by 12 if the number is divisible by both 4 and 3.
  1. Divisibility Rule of 4:

The number formed by the last two digits of the number is divisible by 4.

2. Divisibility Rule of 3:

If the sum of digits is divisible by 3.

In the three problems, the first two only is divisible by 12. Because the last one is divisible by 3 but it is not divisible by 4.
