To make the number sentence correct, what number should be added to 106 to equal 158?
- A.
52
- B.
152
- C.
158
- D.
264
Correct Answer
A. 52Explanation
To find the missing number in the equation 106 + ? = 158, we use subtraction. Since addition and subtraction are inverse operations, we can "undo" the addition by subtracting 106 from the total (158). This gives us: 158 - 106 = 52. Therefore, 52 is the number that needs to be added to 106 to reach 158. This concept highlights the relationship between addition and subtraction in solving for unknowns.Rate this question:

1/3
Correct Answer
B. 2/3Explanation
To find the simplest form of 16242416​, you can simplify the fraction by dividing both the numerator (16) and the denominator (24) by their greatest common factor.
Factors of 16: 1, 2, 4, 8, 16
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
The greatest common factor is the largest number that appears in both lists. In this case, the greatest common factor of 16 and 24 is 8.
Now, divide both the numerator (16) and the denominator (24) by the greatest common factor:
16/24=16÷8/24÷8=2/3

Which of these numbers have only two factors, one and the number itself?
- A.
37+1
- B.
37+37
- C.
37X1
- D.
37X37
Correct Answer
C. 37X1Explanation
A number that has only two factors, one and itself, is called a prime number. Let's evaluate the expressions:
37 + 1 = 38: 38 is not a prime number because it has factors other than 1 and itself (1, 2, 19, and 38).
37 + 37 = 74: 74 is not a prime number because it has factors other than 1 and itself (1, 2, 37, and 74).
37 × 1 = 37: 37 is a prime number because its only factors are 1 and 37.
37 × 37 = 1369: 1369 is not a prime number because it has factors other than 1 and itself (1, 37, and 1369).
Therefore, 37 × 1 = 37 is the number with only two factors, making it the correct answer.Rate this question:

Meena divides a number by 2 and then divides the result by 2 again. What is this equivalent to dividing the original number by?
- A.
1
- B.
4
- C.
6
- D.
It cannot be said as the original number is not known.
Correct Answer
B. 4Explanation
When Meena divides a number by 2, she is finding half of that number. For example, if the original number is xxx, after the first division, the result is x2\frac{x}{2}2x​. When she divides this result by 2 again, she takes half of x2\frac{x}{2}2x​, which can be expressed as x22\frac{\frac{x}{2}}{2}22x​​. This simplifies to x4\frac{x}{4}4x​, indicating that dividing the original number by 2 twice is equivalent to dividing it by 4. Thus, the correct answer is that Meena's process is equivalent to dividing the original number by 4.Rate this question:

John has stamps from different countries. 1/3rd of them are India's stamps. If he has 36 Indian stamps, how many stamps does he have in total?
- A.
12
- B.
36
- C.
48
- D.
108
Correct Answer
D. 108Explanation
If 36 stamps represent one-third (1/3) of John's collection, we need to find out how many stamps are in three-thirds (3/3), which is the whole collection.To do this, we can think:
If 36 stamps = 1/3 of the collection
Then 36 * 3 stamps = 3/3 (the whole) of the collection
So, 36 * 3 = 108 stamps in total.Rate this question:

Meena has bought six pens. The cost of each pen was between Rs.25 and Rs. 30. Which of these could be the total cost of the pens?
- A.
Between Rs. 140 and Rs. 180.
- B.
Rs.126
- C.
Between Rs. 150 and Rs. 180.
- D.
Rs.330
Correct Answer
C. Between Rs. 150 and Rs. 180.Explanation
The total cost of the pens can vary depending on the actual cost of each pen within the given range. To find the possible total cost, we can calculate the minimum and maximum total costs:
Minimum Total Cost: If each pen costs the minimum of Rs. 25, then the minimum total cost for 6 pens would be 6 x Rs. 25 = Rs. 150
Maximum Total Cost: If each pen costs a maximum of Rs. 30, then the maximum total cost for 6 pens would be 6 x Rs. 30 = Rs. 180
So, the possible total cost of the 6 pens could be between Rs. 150 and Rs. 180.Rate this question:

Two angles of a triangle measure 35 degrees and 65 degrees. What is the measure of the third angle of the triangle?
- A.
100 degrees
- B.
80 degrees
- C.
125 degrees
- D.
135 degrees
Correct Answer
B. 80 degreesExplanation
To find the measure of the third angle of a triangle, we use the fact that the sum of the interior angles of a triangle is always 180 degrees.
Given two angles: 35 degrees and 65 degrees.
Sum of the given angles: 35 + 65 = 100 degrees.
Measure of the third angle: 180 - 100 = 80 degrees.
Therefore, the measure of the third angle of the triangle is 80 degrees.Rate this question:

- A.
3
- B.
3/10
- C.
3/100
- D.
3/1000
Correct Answer
C. 3/100Explanation
Place value tells us the "worth" of a digit based on its position in a number. In decimal numbers (numbers with a decimal point), the places to the right of the decimal point represent fractions.
The first place after the decimal is the tenths place (1/10).
The second place is the hundredths place (1/100).
The third place is the thousandths place (1/1000), and so on.
In the number 1.234, the 3 is in the hundredths place. So its place value is 3/100.Rate this question:

- A.
20 cm²
- B.
24 cm²
- C.
40 cm²
- D.
14 cm²
Correct Answer
C. 40 cm²Explanation
The area of a rectangle is found by multiplying the length by the width. Given that the length of the rectangle is 10 cm and the width is 4 cm, we use the formula for area:
Area = length × width = 10 cm × 4 cm = 40 cm².
This formula calculates the total surface area within the rectangle’s boundaries. By multiplying the two dimensions, we account for the entire space enclosed by the length and width. The result, 40 cm², represents the total area in square centimeters, emphasizing the two-dimensional nature of the shape.Rate this question:
