Test: House of Hundreds - I (Part 1) - Class 3 MCQ

To arrange the numbers in descending order, we need to compare the numbers and start with the largest:

1. 946 is the largest number.
2. 835 is the next largest number.
3. 712 comes after 835.
4. 689 is the smallest.

So, when arranged from the largest to smallest: 946, 835, 712, 689.

Comparing the numbers, 758 is greater than 587 because the hundreds place in 758 is 7, while in 587 it is 5. Therefore, 758 is the larger number.

To increase 345 by 50, simply add 50 to 345:

345 + 50 = 395.

In the number 8792, the digit 7 is in the hundreds place. So, the value of the digit 7 is 700.

If you add 100 to 200, you get:

200 + 100 = 300.

The number 496 is less than 500, while the other numbers (519, 540, and 621) are greater than 500.

The smallest 4-digit number is 1000. The predecessor of 1000 is 999, which is the largest 3-digit number.

The total number of candies in the four boxes is 282. The candies in the first three boxes are:
72 + 85 + 67 = 224.
To find the number of candies in the fourth box, subtract the sum of the first three boxes from the total: 282 - 224 = 58 candies.

To increase the number 285 by 1, simply add 1 to it: 285 + 1 = 286.

To form the smallest 3-digit number, arrange the digits in ascending order: 2 < 3 < 7, so the smallest number is 237.
