Step-by-step explanation:

9999991,9999992,9999993,9999994,9999995,9999996,9999997,9999998,999999,100000000

Answer 2

Given:

1) A 7-digit number

2) Digits are in ascending order

3) Gives the same answer when rounded off to nearest thousands or ten thousands

To Find:

The number

Solution:

Ascending order:

⇒  smallest to the biggest

To gives the same answer when rounded off to nearest thousands or ten thousands:

⇒ the digit in the thousands place must be a zero.

The digits in the number must be ascending:

⇒ Since the 4th digit needs to be a "zero", it is not possible to have all the digits ascending.

⇒ If we ignore the middle digit, the rest can be in ascending order

⇒ An example is 1230456

Answer: There is no possible answer, but if we ignore the middle digit with the rest ascending, the number can be 1230456.
