Test: Numbers - 1 - Class 3 MCQ

Standard numeral for Eight thousand fifty

The number eight thousand fifty is written in standard form as:

• 8050

This standard numeral represents:

• 8000 (the thousands place)
• 50 (the tens and units place)

When combining these, you arrive at the correct numeral: 8050.

The greatest two-digit number is 99. Here’s why:

• Two-digit numbers range from 10 to 99.
• The number 99 is the highest value within this range.
• It is the last number before moving into three-digit numbers.

Thus, the answer is clear: 99 is the greatest two-digit number.

One less than 3040 is obtained by subtracting one from the number.

The calculation is as follows:

• Start with 3040.
• Subtract 1 from 3040.
• The result is 3039.

Therefore, the correct answer is 3039.

To determine which number has the digit 3 in the hundreds place, we analyze the positions of the digits in each option:

• Thousands place: 4th digit from the right

• Hundreds place: 3rd digit from the right

• Tens place: 2nd digit from the right

• Ones place: 1st digit from the right

Analysis of Options:

1. A: 1340

   • Digits: 1 (thousands), 3 (hundreds), 4 (tens), 0 (ones).

   • Hundreds place = 3 

2. B: 2453

   • Digits: 2 (thousands), 4 (hundreds), 5 (tens), 3 (ones).

   • Hundreds place = 4 

3. C: 8263

   • Digits: 8 (thousands), 2 (hundreds), 6 (tens), 3 (ones).

   • Hundreds place = 2 

4. D: 3487

   • Digits: 3 (thousands), 4 (hundreds), 8 (tens), 7 (ones).

   • Hundreds place = 4 

The number with 3 in the hundreds place is 1340 (Option A).

The smallest 4-digit number is a fundamental concept in mathematics.

• A 4-digit number is defined as any number ranging from 1000 to 9999.
• The first number in this range, which qualifies as a 4-digit number, is 1000.
• Numbers smaller than 1000, such as 999 or 10, do not have four digits.

Thus, the answer is clear: the smallest 4-digit number is 1000.

To determine the correctness of the statements:

• Statement A claims that 9758 is less than 8579. This is incorrect, as 9758 is greater than 8579.

• Statement B suggests that 7598 is greater than 7958. This is also incorrect; 7598 is less than 7958.

• Statement C states that 5978 equals 8795. This is false because 5978 is not equal to 8795.

• Statement D indicates that 7598 is less than 7958. This statement is true; 7598 is indeed less than 7958.

The only correct statement is D.

The smallest 4-digit number that can be formed using the digits 0 and 5 is 5000. Here’s how we arrive at this conclusion:

• The first digit cannot be 0, as that would not make it a 4-digit number.
• Using 5 as the first digit is essential to ensure it remains a 4-digit number.
• The remaining three digits can be 0 to achieve the smallest value.

Therefore, by placing 5 in the thousands place and 0 in the other three places, we get 5000 as the answer.

The digit 8 appears in several numbers, but its value varies depending on its position.

• In 9358, the 8 is in the units place, contributing a value of 8.
• In 8350, the 8 is in the thousands place, giving it a value of 8000.
• In 7852, the 8 is again in the tens place, contributing a value of 80.
• In 1580, the 8 is in the units place, adding 8 to the total.

Among these options, the position of the digit 8 in 8350 gives it the greatest value of 8000.

The greatest even number that can be formed using the digits 9, 0, 2, and 8 is determined by following these steps:

• To create the largest even number, we must end with an even digit. The available even digits are 0, 2, and 8.
• Among these, 8 is the largest digit, so we will use it at the end.
• The remaining digits to arrange are 9, 0, and 2.
• To maximise the number, we should arrange the remaining digits in descending order.
• The highest arrangement of 9, 2, and 0 is 920.

Combining these, the largest even number we can form is 9820.

The successor of 3000 + 29 is calculated by simply adding 1 to the total sum. Here’s how you can understand it:

• Add the numbers: 3000 + 29 = 3029
• The next number after 3029 is 3030.

Thus, the correct answer is 3030.
