Answer 2

(a.) Therefore the greatest 6-digit number formed by using the digits 0, 1, 3, 4, 7, and 9 is '974310'. ( Option - ii )

(b.) Therefore the period of the digits in the number 6,54,321 is '3'. ( Option - ii )

(c.) The smallest 6-digit number among the given options is '1,00,000'. ( Option - iv )

(d.) Therefore the sum of the place value of 9 and 7 in the number 947635 is 1,01,000. ( Option - iii )

(e.) Therefore the value of 8 × 1,00,000 + 5 × 10,000 + 6 × 1,000 + 9 × 100 + 0 + 5 is 8,56,905. ( Option - ii )

Given:

The given digits are 0, 1, 3, 4, 7, and 9.

To Find:

(a.) The greatest 6-digit number is formed by using the digits 0, 1, 3, 4, 7, and 9.

(b.) The period of the digits in the number 6,54,321.

(c.) The smallest 6-digit number among the given options.

(d.) The sum of the place value of 9 and 7 in the number 947635.

(e.) 8 × 1,00,000 + 5 × 10,000 + 6 × 1,000 + 9 × 100 + 0 + 5

Solution:

This is a simple question with an easy solution as shown below.

(a.) The greatest 6-digit number is formed by using the digits 0, 1, 3, 4, 7, and 9:

The given digits are 0, 1, 3, 4, 7, and 9.

As repeating is not allowed the greatest number comes in lakh places and the next greatest number comes in ten thousand places and so on.

So the number comes out to be '974310'.

Therefore the greatest 6-digit number formed by using the digits 0, 1, 3, 4, 7, and 9 is '974310'.

(b.) The period of the digits in the number 6,54,321:

The period is a type of notation in which a number is divided into groups that consist of 3 numbers each.

To find the period the given number should be written as '654,321'.

Or in lakhs system,

The number is 6,54,321 So the period is '3'.

Therefore the period of the digits in the number 6,54,321 is '3'.

(c.) The smallest 6-digit number among the given options:

Given options: (i) 1,11,111 (ii) 1,00,001 (iii) 1,10,010 (iv) 1,00,000

The smallest 6-digit number among the given options is '1,00,000'.

(d.) The sum of the place value of 9 and 7 in the number 947635:

The place value of '9' in the number 947635= 1,00,000

The place value of '7' in the number 947635 = 1,000

The sum of the place value of 9 and 7 in the number 947635 = 1,00,000 + 1,000 = 1,01,000

Therefore the sum of the place value of 9 and 7 in the number 947635 is 1,01,000.

(e.) 8 × 1,00,000 + 5 × 10,000 + 6 × 1,000 + 9 × 100 + 0 + 5:

⇒ 8 × 1,00,000 = 8,00,000

⇒ 5 × 10,000 = 50,000

⇒ 6 × 1,000 = 6,000

⇒ 9 × 100 = 900

⇒ 0 + 5 = 5

Now, 8 × 1,00,000 + 5 × 10,000 + 6 × 1,000 + 9 × 100 + 0 + 5 = 8,00,000 + 50,000 + 6,000 + 900 + 5 = 8,56,905.

Therefore the value of 8 × 1,00,000 + 5 × 10,000 + 6 × 1,000 + 9 × 100 + 0 + 5 is 8,56,905.

(a.) Therefore the greatest 6-digit number formed by using the digits 0, 1, 3, 4, 7, and 9 is '974310'.

(b.) Therefore the period of the digits in the number 6,54,321 is '3'.

(c.) The smallest 6-digit number among the given options is '1,00,000'.

(d.) Therefore the sum of the place value of 9 and 7 in the number 947635 is 1,01,000.

(e.) Therefore the value of 8 × 1,00,000 + 5 × 10,000 + 6 × 1,000 + 9 × 100 + 0 + 5 is 8,56,905.
