Question

A 4-digit number is formed by repeating a 2-digit number such as 2525, 3232, etc. Any number of this form is always exactly divisible by select one:

Answer 1

If we consider the number which is in repetition such as

2525 = 25 × 101

3232 = 32 × 101

Such that we see 101 is repeated every time which is smallest 3 digit prime number.

Answer 2

Answer:

Smallest 3-digit prime number - 101

Step-by-step explanation:

Missing point in question :- Any number of this form is exactly divisible by 7      (b) 11     (c) 13     (d) Smallest 3-digit prime number

Answer :-

2525/7 - 360.7 Hence it is not divisible by 7.

2525/11 - 229.5 Hence it is not divisible by 11.

2525/13 - 194.2 Hence it is not divisible by 13.

Smallest 3-digit prime number is 101.

2525/101 = 25

3232/101 = 32

abab/101 = ab

So, answer is 101.
