The place value of each digit in the number 57930 is given below in the table:

Hence, the place value of 7 is 7000

Option 'A' is correct.

• The term "successor" refers to the number that comes immediately after a given number.
• To find the successor of 586728932, you simply add 1 to it.
• So, 586728932 + 1 = 586728933
• Option 'A' is correct.

• The term "predecessor" refers to the number that comes immediately before a given number.
• To find the predecessor of 88899025, you simply subtract 1 from it.
• So, 88899025 - 1 = 88899024.
• Option 'A' is correct.

A 7-digit number is a number that has seven digits, where the first digit cannot be zero. The largest possible digit in any position is 9. So, to form the largest 7-digit number, we place 9 in all seven positions.

Let's break it down:

• The first digit (millions place) can be 9.
• The second digit (hundreds of thousands place) can be 9.
• The third digit (ten thousands place) can be 9.
• The fourth digit (thousands place) can be 9.
• The fifth digit (hundreds place) can be 9.
• The sixth digit (tens place) can be 9.
• The seventh digit (ones place) can be 9.

Therefore, the largest 7-digit number is:

9999999

So, the correct answer is A) 9999999.

1. 1 crore is a unit of measurement commonly used in India and other South Asian countries. It is equivalent to 10 million in the international numbering system, which is 10,000,000.

2. 1 lakh is another unit used in India, which is equivalent to 100,000.

Now, let's break it down:

• 1 crore = 10,000,000.
• 1 lakh = 100,000.

To find how many ten lakh make up 1 crore:

1 crore = 10,000,000
1 ten lakh = 1 lakh × 10 = 1,000,000.

Now, divide 1 crore by 1 ten lakh:

Therefore, 1 crore = 10 ten lakh.

So the correct answer is: 1 crore = 10 ten lakh.

In the Indian numbering system:

1. 1 lakh = 100,000 (one hundred thousand).

Now, we need to find how many lakh make up 100 thousands.

• 100 thousands = 100 × 1,000 = 100,000.

So, 100 thousands is exactly equal to 1 lakh.

Step-by-step breakdown:

• 1 thousand = 1,000.
• 100 thousands = 100 × 1,000 = 100,000.
• 1 lakh = 100,000.

Therefore, 100 thousands is equal to 1 lakh.

So the correct answer is: (B) 1.

1 million = 10 lakh (in the Indian numbering system).

Now, we need to calculate one-fifth of a million:

Since 1 lakh = 100,000, we can convert 200,000 into lakhs:

So, one-fifth of a million = 2 lakh.

Therefore, the correct answer is: (C) 2 lakh.

1 crore = 10 lakh.

Now, for 7000 lakh:

7000 lakh = 7000 × 1,00,000 = 70,00,00,000

We know that 1 crore = 1,00,00,000. So, to convert 70,00,00,000 into crores:

Therefore, 7000 lakh = 70 crores.

So the correct answer is: (D) 70 crores.

The number is 13,67,89,542.

To identify the ten lakh place in the number 13,67,89,542; refer to the following table

Thus, the correct answer is 6.

Option 'C' is correct.

• To find the place value of 7 in the number 478123546, refer tot the following table
• The place value position of digit 7 in 478123546 is ten million
  as One million has 6 zeros after 1 and 10 million has 7 zeros after 1.
• Option 'A' is correct.
