The given numbers in the descending order are:

1712040 > 1704382 > 1702497 > 201200 > 200175 >199988

Arrange the following numbers in ascending order:

11. 9873426, 24615019, 990357, 9874012, 24620010

Solution

9873426 and 9874012 are both 7-digits numbers in which the same numbers 9, 8 and 7 are placed at ten lakhs, lakhs and ten thousands places respectively and the digits 3 and 4 are placed at thousands places

Since 3 < 4

Hence 9873426 < 9874012

24615019 and 24620010 are both 8-digits numbers in which the same numbers 2, 4 and 6 are placed at crores, ten lakhs and lakhs respectively, since 2 and 1 are ten thousands place

Hence 24615019 < 24620010

The given numbers in ascending order are:

990357 < 9873426 < 9874012 < 24615019 < 24620010

12. 56943201, 5694437, 56944000, 5695440, 56943300

5694437 and 5695440 are both 7-digits numbers in which the same numbers 5, 6 and 9 are placed at ten lakhs lakhs and ten thousands places respectively and the digits 4 and 5 are at thousand places

Since 4 < 5

Hence 5694437 < 5695440

56943201, 56943300 and 56944000 are all 8-digits numbers

The same numbers 5, 6, 9 and 4 are placed at crores, ten lakhs, lakhs and ten thousands place

The digits 3 and 4 are at thousands place

Since 3 < 4

56943300 < 56944000

The digits 2 and 3 are at hundreds place

Since 2 < 3

56943201 < 56943300

The given numbers in ascending order are:

5694437 < 5695440 < 56943201 < 56943300 < 56944000

13. 700087, 8014257, 8015032, 10012458, 8014306

Solution

700087 is 6-digit number

8014257, 8015032 and 8014306 are all 7-digit numbers

The same numbers 8, 0 and 1 are placed at ten lakhs, lakhs and ten thousands place respectively

At thousands place one number has 5 while the other two numbers have 4

Hence 8015032 is the largest number

The digits 2 and 3 are at hundreds place in the remaining two numbers

Hence 8014257 < 8014306

10012458 is an 8 digit number

The given numbers in ascending order are:

700087 < 8014257 < 8014306 < 8015032 < 10012458

14. 1020304, 893245, 980134, 1021403, 893425, 1020216

Solution

893245, 893425 and 980134 are 6-digits number

980134 is the largest number

The same numbers in the remaining two numbers are 8, 9 and 3 are placed at lakhs, ten thousands and thousands places respectively and the digits 2 and 4 are at hundreds place

Hence 893245 < 893425

1020304, 1021403 and 1020216 are all 7-digits number

Since they have the same digits at ten lakhs, lakhs and ten thousand places namely 1,0 and 2 respectively

1021403 has 1 at thousand places and the remaining two numbers have the digits at hundred places namely 2 and 3

Since 2 < 3

∴ 1020216 < 1020304

Hence, the given numbers in ascending order are

893245 < 893425 < 980134 < 1020216 < 1020304 < 1021403
