Test: Numeration - 1 - Class 4 MCQ

The correct answer is A
A  five-digit number is represented using a place value chart divided into two periods: Ones and Thousands.

A 4-digit number must have at least four digits. The smallest 4-digit number is formed by the smallest digit (1) in the thousands place followed by three zeros. Therefore, 1,000 is the smallest number that has four digits.

The place value of a number is the value of the digit in the given number.
The place value of the underlined digit in the number 7,65,730 is 7,00,000 as it is in the lakhs place.

The face value of a digit in a number is the value of the digit itself, regardless of its position.

In the number 2,859: The digit 5 is in the tens place, but its face value is simply 5.

To clarify further, here are the values of each digit in the number 2,859:

• 2 is in the thousands place (2,000)
• 8 is in the hundreds place (800)
• 5 is in the tens place (50)
• 9 is in the ones place (9)

However, when asked for the face value of 5, we only consider the digit itself, which is 5.

4 x Lakh + 5 x Ten-Thousand + 0 x Thousand + 0 x Hundred + 0 × Ten + 0 × One

= 4 x 100000 + 5 x 10000 + 0 x 1000 + 0 x 100 + 0 x 10 + 0 x 1

= 400000 + 50000 + 0 + 0 + 0 + 0

= 400000 + 50000

= 450000

= Four Lakh fifty thousands

1,00,000 is equal to 100 thousands.
1,00,000 is read as one lakh.
Hence, 1,00,000 can be expressed as 100 thousands.

There are three ten thousands, five thousands, six hundreds, three tens and five ones in the number 35,635. Hence, we read 35,635 as thirty-five thousand six hundred and thirty-five.

• Start with the largest place value: 40,000.
• Add the next place value: 6,000, making 46,000.
• Add 700 to get 46,700.
• Add 80 to reach 46,780.
• Finally, add 1 to make 46,781.

99,999 is the greatest 5-digit number.
When 1 is added to 99,999, we get the 6-digit number 1,00,000.

There are 2 beads in the lakhs place, 4 beads in the ten thousands place, 6 beads in the thousands place, 0 beads in the hundreds place, eight beads in the tens place and one bead in the ones place.
Hence, the number on the abacus is 2,46,081.
