Olympiad Test: Numbers - 1 - Class 2 MCQ

456 < 465 < 546

552 is not equal to 550.

• A: 400, 500, 600


• B: 496, 497, 498


• C: 499, 500, 501


• D: 500, 501, 502

Explanation:

• A: 400, 500, 600 - This sequence has a difference of 100 between each number, making it the odd one out.


• B: 496, 497, 498 - This sequence has a difference of 1 between each number.


• C: 499, 500, 501 - This sequence has a difference of 1 between each number.


• D: 500, 501, 502 - This sequence has a difference of 1 between each number.

Therefore, the odd one out is sequence A: 400, 500, 600 as it does not follow the pattern of a consecutive sequence or a sequence with a common difference.

• To find how many tens are in 43, we need to look at the tens place in the number.
• The number 43 has a '4' in the tens place, which means there are 4 full tens.
• Thus, we can say that 43 contains 4 tens (40) and 3 units (3).
• Therefore, the correct answer is that it has 4 tens.

 Since 43 is a two-digit number. Hence place value of 4 is tens and 3 is ones.

Looking at the image, let's examine each option to see which is incorrectly matched:

• (A) 348: The ones' place digit is 8, which is correct.
• (B) 4397: The hundreds' place digit is 3, which is correct.
• (C) 596: The tens' place digit is 9, not 5, so this is incorrect.
• (D) 23: The ones' place digit is 3, which is correct.

Thus, the incorrectly matched pair is (C) 596 – Its tens' place digit is 5.

In a three-digit number, the three place values are One’s place, Ten’s place and Hundred’s place.
Digit at one’s place = 5
Digit at ten’s place = 9
The digit present at hundreds place is three more than the number present at ones place = 5 + 3 = 8
Digit at hundred’s place = 8
So, the number is 895 and its number name is eight hundred and ninety-five.
Hence, option (b) is the correct answer.
