    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. 37X1

    Explanation
    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.

    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. 4

    Explanation
    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:

  • 8.

    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. 108

    Explanation
    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.

  • 9.

    1024+1025+___=1025+1025+1025What number will come in the blank to make the number sentence correct?

    • A.

      1024

    • B.

      1025

    • C.

      1026

    • D.

      5124

    Correct Answer
    C. 1026

    Explanation
    This question is like a balance scale. To keep it balanced, both sides need to have the same total weight.

    Right side: 1025 + 1025 + 1025 = 3075
    Left side: We have 1024 + 1025 = 2049

    To make the left side equal 3075, we need to find the difference: 3075 - 2049 = 1026

    So, 1026 is the missing number.

  • 10.

    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.

    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 degrees

    Explanation
    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:

  • 12.

    What is the sum of any THREE angles of a rectangle?

    • A.

      90 degrees

    • B.

      180 degrees

    • C.

      270 degrees

    • D.

      360 degrees

    Correct Answer
    C. 270 degrees

    Explanation
    A rectangle has four right angles, and each angle measures 90 degrees. The sum of all four angles in a rectangle is 360 degrees (4 × 90 = 360). If you add up the measures of any three angles in a rectangle, the total will be 270 degrees (3 × 90 = 270). Thus, the correct answer is 270 degrees.

    Rate this question:

    What is the ratio of 500 ml to 2 liters?

    • A.

      1:4

    • B.

      1:6

    • C.

      1:8

    • D.

      1:10

    Correct Answer
    A. 1:4

    Explanation
    To find the ratio, we need to ensure both quantities are in the same units. Since 1 liter equals 1000 milliliters, 2 liters is 2000 milliliters. So, the ratio is 500 ml to 2000 ml. To simplify, we divide both sides by the greatest common factor, which is 500. This gives us 500/500 : 2000/500, simplifying to 1:4. Therefore, the ratio of 500 ml to 2 liters is 1:4.

      55

    • C.

      75

    • D.

      85

    Correct Answer
    A. 65

    Explanation
    To solve the question 15 × (3 + 2) - 10, follow these steps:

    1. Evaluate the expression inside the parentheses:
    3+2=53 + 2 = 53+2=5.

    2. Multiply the result by 15:
    15×5=7515 × 5 = 7515×5=75.

    3. Subtract 10 from the product:
    75−10=6575 - 10 = 6575−10=65.

    Thus, the final answer is 65

    What is the place value of 3 in 1.234?

    • A.

      3

    • B.

      3/10

    • C.

      3/100

    • D.

      3/1000

    Correct Answer
    C. 3/100

    Explanation
    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.

    How many minutes are in 3 hours?

    • A.

      120

    • B.

      150

    • C.

      180

    • D.

      240

    Correct Answer
    C. 180

    Explanation
    To find how many minutes are in 3 hours, we use the fact that 1 hour equals 60 minutes. Multiply the number of hours by 60:
    3 × 60 = 180 minutes.
    Thus, there are 180 minutes in 3 hours. This calculation is straightforward, as the relationship between hours and minutes is a basic multiplication problem. By understanding the conversion factor between hours and minutes, we can easily calculate the total number of minutes for any number of hours. The answer, 180 minutes, is obtained by multiplying and confirming that each hour has a consistent 60-minute duration.

    What is the perimeter of a square with each side measuring 7 cm?

    • A.

      28 cm

    • B.

      21 cm

    • C.

      14 cm

    • D.

      49 cm

    Correct Answer
    A. 28 cm

    Explanation
    The perimeter of a square is calculated by adding all four sides. Since a square has equal sides, the formula for the perimeter is side length × 4. Given that each side of the square measures 7 cm, the perimeter is
    7 cm × 4 = 28 cm.
    This is a straightforward calculation, where we multiply the side length by 4 to account for each of the four sides of the square. The concept relies on understanding the geometric property that all sides of a square are equal, leading to the formula for the perimeter.

    If a pizza is divided into 8 equal slices, what fraction of the pizza is 3 slices?

    • A.

      3/8

    • B.

      1/4

    • C.

      1/2

    • D.

      5/8

    Correct Answer
    A. 3/8

    Explanation
    When a pizza is divided into 8 equal slices, each slice represents 1/8 of the pizza. To find the fraction of the pizza that 3 slices represent, multiply the fraction of one slice by 3:
    1/8 × 3 = 3/8.
    This calculation shows that 3 slices constitute 3 out of 8 parts of the pizza. Fractions represent parts of a whole, and this problem requires multiplying the unit fraction by the number of slices. The resulting fraction, 3/8, expresses the part of the pizza that has been selected.

      8

    • C.

      9

    • D.

      10

    Correct Answer
    C. 9

    Explanation
    To find how many days it will take to sell all 45 apples if 5 apples are sold per day, divide the total number of apples by the number sold each day:
    45 ÷ 5 = 9 days.
    This division tells us that it will take 9 days to sell all the apples at the given rate. This is a simple division problem, where the total amount is divided evenly by the number sold per day. The result, 9 days, is the time required for all apples to be sold at a consistent rate of 5 apples daily.

    A rectangle has a length of 10 cm and a width of 4 cm. What is its area?

    • A.

      20 cm²

    • B.

      24 cm²

    • C.

      40 cm²

    • D.

      14 cm²

    Correct Answer
    C. 40 cm²

    Explanation
    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.
