7. 63521047, 7354206, 63514759, 7355014, 102345680

Solutions

Here 102345680 is a 9-digit number

63521047 and 63514759 are both 8-digit numbers in which the same numbers namely 6,3, and 5 are placed at crores, ten lakhs and lakhs place respectively whereas 2 and 1 are placed at ten thousands place

Since 2 > 1

Therefore 63521047 > 63514759

7354206 and 7355014 are both 7-digits numbers

Here the same numbers 7, 3 and 5 are placed at crores, ten lakhs and lakhs place respectively whereas 5 and 4 are placed at ten thousands place

Since 5 > 4

Therefore 7355014 > 7354206

The given numbers in the descending order are:

102345680 > 63521047 > 63514759 > 7355014 > 7354206

8.5032786, 23794206, 5032790, 23756819, 987876

Solution

Here 23794206 and 23756819 are both 8-digits numbers in which the same numbers 2,3 and 7 are placed ten lakhs, lakhs, ten thousands, thousands and hundreds places respectively whereas 9 and 5 are placed at tens place respectively.

Since 9 > 5

Therefore 23794206 > 23756819

Here 5032786 and 5032790 are both 7-digits numbers in which the same numbers 5,0,3,2 and 7 are

Placed at ten lakhs, lakhs, ten thousands, thousands and hundreds places respectively whereas 9 and 8 are placed at tens place respectively.

Since 9 > 8

Therefore 5032790 > 5032786

987876 is a 6-digits number

The given numbers in the descending order are:

23794206 > 23756819 > 5032790 > 5032786 > 987876

9.190909, 1808088, 16060666, 16007777, 181888, 1808090

Solution

Here 16060666 and 16007777 are 8-digits numbers in which the same numbers 1, 6 and 0 are placed at crores, ten lakhs and lakhs respectively whereas 6 and 0 are placed at ten thousands place respectively

Since 6 > 0

Therefore 16060666 > 16007777

1808088 and 1808090 are both 7-digits numbers in which the same numbers 1, 8, 0, 8 and o are placed at ten lakhs, lakhs, ten thousands, thousands and hundreds places respectively whereas 9 and 8 are placed at tens place respectively

Since 9 > 8

Therefore 1808090 > 1808088

190909 and 181888 are both 6-digits numbers

In both the numbers the same digit 1 is at lakhs place and the digits at ten thousands place are 9 and 8

Since 9 > 8

Therefore 190909 > 181888

The given numbers in the descending order are:

16060666 > 16007777 > 1808090 > 1808088 > 190909 > 181888

10.199988, 1704382, 200175, 1702497, 201200, 1712040

Solution

Here 1712040, 1704382 and 1702497 are all 7-digits numbers in which the same numbers 1 and 7 are placed at ten lakhs and lakhs places respectively whereas the digits in ten thousands place are 1, 0 and 0

Hence 1712040 is the largest number and the digits in the remaining two numbers at thousands place are 4 and 2

Since 4 > 2

Therefore 1704382 > 1702497

201200, 200175 and 199988 are 6-digits numbers in which 2 and 1 are at lakhs place respectively

Since 2 is greater than 1

Therefore 201200 > 200175

Thus 199988 is the smallest number

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

Solution

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
