Gunjan Lakhani answered |
To solve this, let's first find the sum of 178 and 69:
178+69=247
Now, we round 247 to the nearest hundred.
- The nearest hundred to 247 is 200 because 247 is closer to 200 than to 300.
So, the sum of 178 and 69 rounded to the nearest hundred is 200.

Understanding Square Numbers
Square numbers are the product of an integer multiplied by itself. For example, \( n^2 \) (where \( n \) is an integer) gives us square numbers. The first few square numbers are:
- \( 1^2 = 1 \)
- \( 2^2 = 4 \)
- \( 3^2 = 9 \)
- \( 4^2 = 16 \)
- \( 5^2 = 25 \)
- \( 6^2 = 36 \)
Identifying Square Numbers Among Options
Let's analyze the options provided:
- a) 20: This is not a square number. The closest integers are \( 4^2 = 16 \) and \( 5^2 = 25 \).
- b) 24: This is also not a square number. It falls between \( 4^2 = 16 \) and \( 5^2 = 25 \).
- c) 25: This is a square number, as it equals \( 5^2 \).
- d) 30: This is not a square number. The square numbers surrounding it are \( 5^2 = 25 \) and \( 6^2 = 36 \).
Conclusion
Thus, among the options provided, 25 (option c) is the only square number because it can be expressed as \( 5 \times 5 \). Understanding how to identify square numbers is essential in mathematics, especially in recognizing patterns and solving problems in number theory.

Subset Academy answered |
To find the approximate length of Sita's ribbon, we need to subtract 1232 mm from Rita's ribbon length and then round the result to the nearest hundred.
Rita's ribbon length = 2070 mm Sita's ribbon length = Rita's ribbon length - 1232 mm
Sita's ribbon length β 2070 mm - 1232 mm Sita's ribbon length β 838 mm
When rounded to the nearest hundred, Sita's ribbon length is approximately 800 mm.
Rita's ribbon length = 2070 mm Sita's ribbon length = Rita's ribbon length - 1232 mm
Sita's ribbon length β 2070 mm - 1232 mm Sita's ribbon length β 838 mm
When rounded to the nearest hundred, Sita's ribbon length is approximately 800 mm.

Even Prime Number
An even number is a number that is divisible by 2. However, the only even prime number is 2. Here's why:
Explanation
- A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.
- Even numbers are divisible by 2, which means they have 2 as a factor.
- The only even number that meets the definition of a prime number is 2 because it has no other factors besides 1 and 2.
- All other even numbers, such as 4, 6, 8, etc., have factors other than 1 and themselves, making them composite numbers.
Therefore, the even prime number is 2, making option 'B' the correct answer.

Vp Classes answered |
During the finals, 10050 tickets were sold, whereas for the semi-final match, only 9872 tickets were sold. To find out how many more tickets were sold during the finals, we subtract the number of tickets sold for the semi-finals from the number of tickets sold during the finals. Therefore, 10050 - 9872 = 178. Since we need to estimate to the nearest tens, the answer would be 180.

- A triangular number is a number that can form an equilateral triangle. The sequence of triangular numbers is: 1, 3, 6, 10, 15, 21, 28, 36, 45, ...
- A square number is a number that is the square of an integer. The sequence of square numbers is: 1, 4, 9, 16, 25, 36, 49, 64, ...
The number 36 appears in both sequences:
- It is the 8th triangular number: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36.
- It is also the 6th square number: 6 * 6 = 36.
Thus, 36 is both a triangular number and a square number.

Understanding the Sequence
The given sequence is: 1, 4, 9, 16...
Each number in this sequence is a perfect square.
Identifying the Pattern
- The first number (1) is \(1^2\).
- The second number (4) is \(2^2\).
- The third number (9) is \(3^2\).
- The fourth number (16) is \(4^2\).
Thus, the pattern is that the \(n\)-th term in the sequence is given by \(n^2\).
Finding the Next Number
To find the next number in the sequence, we need to calculate \(5^2\):
- \(5^2 = 25\)
Conclusion
The next number in the sequence is 25, which corresponds to option 'C'.
- This confirms that the sequence consists of the squares of consecutive integers: \(1^2, 2^2, 3^2, 4^2, 5^2\).
Understanding this pattern is crucial for solving similar problems in the future.

Understanding Three-Dimensional Objects
Three-dimensional (3D) objects have depth, width, and height, making them more complex than two-dimensional (2D) shapes, which only have length and width.
Types of Shapes
- Square:
- A square is a 2D shape with four equal sides and four right angles.
- It exists only on a flat surface.
- Triangle:
- A triangle is also a 2D shape with three sides and three angles.
- Like a square, it is flat and does not have depth.
- Circle:
- A circle is a round, 2D shape characterized by all points being equidistant from the center.
- It also lacks height and depth.
- Cube:
- A cube is a 3D object with six square faces, twelve edges, and eight vertices.
- It has depth, width, and height, making it a solid object.
Why Cube is the Correct Answer
The cube is the only option listed that meets the criteria of being a three-dimensional object. It can be visualized as a box that occupies space and can be measured in three dimensions (length, width, height).
In contrast, the square, triangle, and circle are flat shapes, confined to two dimensions.
Conclusion
In summary, while squares, triangles, and circles are two-dimensional, the cube stands out as the sole three-dimensional shape among the options provided. Understanding these differences is crucial in geometry and helps in visualizing how objects exist in space.

- 15 + 6 = 21 (This is the second missing term)
Conclusion
The pattern is that each term is the sum of the previous term and an increasing integer (1, 2, 3, 4, 5, 6, ...).
Thus, the missing terms in the sequence are:
- The first missing term is 10.
- The second missing term is 21.
Therefore, the correct answer for the first missing term is option 'C', which is 10.
The given sequence is: 1, 3, 6, __, 15, __.
To find the missing terms, we need to identify the pattern in the sequence.
Identifying the Pattern
1. First Term: 1
- The first term is simply 1.
2. Second Term: 3
- 1 + 2 = 3
3. Third Term: 6
- 3 + 3 = 6
4. Fourth Term: __
- 6 + 4 = 10 (This is the first missing term)
5. Fifth Term: 15
- 10 + 5 = 15
6. Sixth Term: __
- 15 + 6 = 21 (This is the second missing term)
Conclusion
The pattern is that each term is the sum of the previous term and an increasing integer (1, 2, 3, 4, 5, 6, ...).
Thus, the missing terms in the sequence are:
- The first missing term is 10.
- The second missing term is 21.
Therefore, the correct answer for the first missing term is option 'C', which is 10.

The price of the school bag is 250 Rs. 95 paise, while Priya has 210 Rs. 25 paise. To determine how much more money she needs, we first convert both amounts into paise.
- 250 Rs. 95 paise = 250 Γ 100 + 95 = 25,095 paise
- 210 Rs. 25 paise = 210 Γ 100 + 25 = 21,025 paise
Next, we subtract the amount Priya has from the total price of the bag:
25,095 paise - 21,025 paise = 4,070 paise
Therefore, Priya requires 4070 paise more to purchase the bag.

The smallest 5-digit number is 10000, while the largest 4-digit number is 9999.
To determine the difference:
- 10000 - 9999 = 1
This shows that the smallest 5-digit number is greater than the largest 4-digit number by 1.
The correct answer is d) 1.

Praveen Kumar answered |
First, add the numbers:
267 + 132 = 399
Now, round 399 to the nearest ten. Since the last digit (9) is 5 or greater, we round up to the next ten:
399 rounded to the nearest ten is 400.
So, the correct answer is D: 400.

In Roman numerals:
- 400 is represented as CD.
- C stands for 100, and D stands for 500.
- Since 400 is 500 minus 100, it is written as CD.
Thus, the correct answer is A: CD.

Dr Manju Sen answered |
1 million is equal to 1,000,000. To find out how many thousands are in a million, we can use the following steps:
- Recognise that 1 thousand equals 1,000.
- Divide 1,000,000 by 1,000:
- 1,000,000 Γ· 1,000 = 1000.
Therefore, 1 million is equal to 1000 thousands.

Vp Classes answered |
We are given the equation:
15 Γ 1000 + 7 Γ _______ + 6 Γ 10 = 15760
Let's simplify the known values first:
- 15 Γ 1000 = 15000
- 6 Γ 10 = 60
Now, substitute these values into the equation:
15000 + 7 Γ _______ + 60 = 15760
Subtract 15000 and 60 from 15760:
15760 - 15000 - 60 = 700
So, the missing value is:
7 Γ _______ = 700
To find the missing value, divide 700 by 7:
700 Γ· 7 = 100
Thus, the missing value is 100.
So, the correct answer is C: 100.

EduRev Class 6 answered |
To round 28,549 to the nearest hundred, follow these steps:
- Identify the tens place, which is 4.
- Since 4 is less than 5, we round down.
- This keeps the hundreds place the same.
Therefore, 28,549 rounded to the nearest hundred is 28,500.
The correct answer is B: 28,500.

To find the smallest natural number that rounds off to 500 when rounded to the nearest hundred, consider the range of numbers that round to 500.
- Numbers from 450 to 549 round off to 500 when rounded to the nearest hundred.
- Therefore, the smallest number that rounds to 500 is 450.
So, the correct answer is C: 450.
