Test: Large Numbers- 1 - Class 5 MCQ

The largest 7-digit number is 99,99,999.
It comes just before the smallest 8-digit number 1,00,00,000.

Step 1: Count the number of digits in each number. 1000 and 3222 has 4 digits whereas 111 and 225 has three digits.
Step 2: The number with less number of digits < The numbers with more number of digits

So, options b and d are not the required options
Step 3: Compare 111 and 225
Compare the hundreds digits. The hundreds digit in 111 is 1.
The hundreds digit in 225 is 2.
Since 1 < 2, 111 < 225 .

When a given number is rounded off to the nearest ten thousand, check if the digit at the thousands place is more than or equal to 5.
If the number is more than 5, add 1 to the rounding digit and replace all the digits to its right with 0.
Hence, when the number 19,73,19,371 is rounded off to the nearest ten thousand, we get 19,73,20,000.

To determine which set of numbers are consecutive, we need to compare the numbers sequentially to see if they increase by 1 each time. Here are the options provided:

1. 1,23,45,345 , 1,23,45,237 , 1,23,55,221 , 1,37,29,200

   These numbers do not form a sequence of consecutive numbers.

2. 1,23,45,345 , 1,23,45,346 , 1,23,45,347 , 1,23,45,348

   These numbers form a sequence of consecutive numbers, as each number increases by 1 from the previous number.

3. 1,15,15,345 , 1,23,45,237 , 1,23,45,221 , 1,17,19,200

   These numbers do not form a sequence of consecutive numbers.

4. 1,23,45,400 , 1,52,45,900 , 1,23,55,200 , 1,37,29,500

   These numbers do not form a sequence of consecutive numbers.

Therefore, the option that represents consecutive numbers is:

Option 2: 1,23,45,345 , 1,23,45,346 , 1,23,45,347 , 1,23,45,348

3,25,63,367 can be read as Three crore twenty-five lakh sixty-three thousand three hundred sixty-seven.

Correct answer (b)

Explanations: In this series, the numbers are arranged in ascending order from the smallest to the largest, using the less than ("<") sign to indicate that each number is smaller than the next. Here's the explanation for the comparisons:

• 654321 < 876543: This indicates that 654321 is smaller than 876543.
• 876543 < 888888: This shows that 876543 is smaller than 888888.
• 888888 < 987654: This means 888888 is smaller than 987654.
• 987654 < 999999: This indicates that 987654 is smaller than 999999.

So, the entire sequence shows a progression from the smallest number, 654321, to the largest, 999999.

4 lies in the crores place.
The place value of 4 in the number 4,67,13,223,  is 4,00,00,000.

8,00,00,000 + 10,00,000 + 40,000 + 5000 + 300 +70 + 1 is the expanded form of the number 8,10,45,371.

The smallest 8-digit number is 1,00,00,000.
It comes just after the greatest 7-digit number 99,99,999.

67298823 can be written in the international place value chart as:

Hence, it can be read as Sixty-seven million two hundred ninety-eight thousand eight hundred twenty-three.
