  • Question 1
    1 / -0
    Which among the following is ten more than 10 hundreds?
    Solution
    10 hundreds = 10 × 100 = 1000
    Ten more than 10 hundreds = 1000 + 10 = 1010
  • Question 2
    1 / -0
    Using digits 8, 6, 7, 0 and 4 exactly once, what is the largest 5-digit number that can be formed?
    Solution
    The largest 5-digit number should have the largest of the given digits at ten thousands place.
    Also, second largest digit should be at thousands place, third largest digit should be at hundreds place, and so on.

    Thus, the answer is 87640.
  • Question 3
    1 / -0
    Using digits 8, 6, 7, 0 and 4 exactly once, what is the smallest 5-digit number, divisible by 10, that can be formed?
    Solution
    The smallest 5-digit number using digits 8, 6, 7, 0 and 4 exactly once must have the smallest of these digits at ten thousands place, the second smallest digit at thousands place, the third smallest digit at hundreds place, and so on. But if 0 is placed at ten thousands places, then it will become a 4-digit number.
    Also, for a number to be divisible by 10, it must have 0 at the units place.
    So, the required number is 46780.
  • Question 4
    1 / -0
    The difference between the place value of the digit at thousands place and the place of the digit at tens place in 97547 is
    Solution
    The place value of the digit at thousands place in 97547 = 7000
    The place value of the digit at tens place in 97547 = 40
    Required Difference = 7000 - 40 = 6960
  • Question 5
    1 / -0
    Which among the following is not equal to nine thousands?
    Solution
    9 thousands must have 3 zeroes in it.

    Here, 90 hundreds = 9000
    900 tens = 900 x 10 = 9000
    9000 ones = 9000 x 1 = 9000
    9 hundreds = 9 x 100 = 900

    Thus, 9 hundreds is incorrect.
  • Question 6
    1 / -0
    Write the number 78564 in expanded form.
    Solution
    Place value of the digit at ten thousands place in 78564 = 7 x 10000 = 70000
    Place value of the digit at thousands place in 78564 = 8 x 1000 = 8000
    Place value of the digit at hundreds place in 78564 = 5 x 100 = 500
    Place value of the digit at tens place in 78564 = 6 x 10 = 60
    Place value of the digit at units place in 78564 = 4 x 1 = 4
    So, 78564 in expanded form = 70000 + 8000 + 500 + 60 + 4
  • Question 7
    1 / -0
    Arrange the following numbers in descending order:

    500 hundreds, 600 ones, 70 tens, 6 thousands
    Solution
    500 hundreds = 500 × 100 = 50000
    6 thousands = 6 × 1000 = 6000
    70 tens = 70 × 10 = 700
    600 ones = 600 × 1 = 600
    So, descending order: 50000 > 6000 > 700 > 600
    Hence, option (4) is correct.
  • Question 8
    1 / -0
    Which of the following numbers has digit 9 at thousands place?
    Solution
    Thousands place means the place value of the digit must be a multiple of 1000.
    In number 49864, the place value of the digit 9 is 9 x 1000 = 9000.
    Hence, 49864 has 9 at thousands place.
  • Question 9
    1 / -0
    What is the place value of 3 in 3450000?
    Solution
    The place value of 3 in 3450000 = 30,00,000 or 30 lakh
  • Question 10
    1 / -0
    The number ninety-five thousand nine hundred and ninety-nine in digits will be written as
    Solution
    Ninety-five thousand = 95000
    Nine hundred = 900
    Ninety nine = 99
    So, ninety-five thousand nine hundred and ninety-nine = 95000 + 900 + 99 = 95999
  • Question 11
    1 / -0
    1,50,406 = 1 lakh + _____ thousands + 40 tens + 6 ones
    Solution
    1,50,406 = 1 lakh + 50 thousands + 40 tens + 6 ones
  • Question 12
    1 / -0
    The number on the box is supposed to be the best estimate of the actual number of oranges in the box. The actual number of oranges in the box may be

    Solution
    Best estimate is the closest possible value.

    We use rounding of numbers to find the best estimate.

    Here, 295 has to be the actual number of oranges because if we round up 295, we will get 300.
  • Question 13
    1 / -0
    The following table shows the amounts carried by Ajay, Ram, Siya and Divya:

    Rs. 2520 Ajay
    Rs. 2502 Ram
    Rs. 2598 Siya
    Rs. 2589 Divya

    Which of the following statements is CORRECT?
    Solution
    Let's analyse all the options:
    (1) Siya has the highest amount of money, as 2598 is the highest of the given numbers.
    Thus, option 1 is wrong.

    (2) Divya has Rs. 2589.
    Ram has Rs. 2502.
    Siya has Rs. 2598.
    Thus, option 2 is wrong.

    (3) Least amount of money = Rs. 2502, which is carried by Ram.
    Thus, option (3) is correct.

    (4) Siya has Rs. 2598.
    Ajay has Rs. 2520.
    Thus, option (4) is wrong.
  • Question 14

    Roman Numerals I V X L C D M
    Hindu-Arabic Numerals 1 5 10 50 100 500 1000

    What is the value of MDX?
    Solution
    MDX = M + D + X = 1000 + 500 + 10 = 1500 + 10 = 1510
  • Question 17
    1 / -0
    What is the value of 234576 when rounded to the nearest 100000?
    Solution
    To round 234576 to the nearest 100000, we check the digit at ten thousands place.
    If the digit there is less than 5, the number should be rounded down to the nearest multiple of 100000.
    On the other hand, if the digit is 5 or more than 5, the number should be rounded up to the nearest multiple of 100000.

    So, 234576 when rounded to the nearest 100000 will be 200000 as 3 is the digit at ten thousands place, which is less than 5. Therefore, the number should be rounded down.
  • Question 18
    1 / -0
    Which of the numbers given in alternatives should not replace the question mark in the box in order to get a series in ascending order?

    1254 3569 ? 6987
    Solution
    3556 is smaller than 3569, so it cannot come in the box next to it as the sequence is increasing.

  • Question 19
    1 / -0
    Which among the following is the same as 45607?
    Solution
    The expanded form of 45607 is:
    40000 + 5000 + 600 + 0 + 7 = 40000 + 5000 + 600 + 7
  • Question 20
    1 / -0
    34517 is 34500 when rounded to the nearest __________.
    Solution
    All the digits in the number, except the last two, remain the same. Since only the digits at ones place and tens place are changed to zero, therefore the number is rounded to the nearest hundred.
  • Question 21
    1 / -0
    Taruna has a collection of 58647 ping pong balls. Round this number to the nearest thousand.
    Solution
    Digit at hundreds place = 6
    Since 6 is greater than 5, so this number will be rounded up.
    Therefore, 58647, when rounded to the nearest thousand, becomes 59000.

  • Question 29
    1 / -0
    A, B, C and D are six-digit numbers, each having the digit 0 only once and at the place shown in the table below. None of the other digits is known.
    Which of the following statements is certainly correct about A, B, C or D?

    A
    100000s 10000s 1000s 100s 10s 1s
    0

    B
    100000s 10000s 1000s 100s 10s 1s
    0

    C
    100000s 10000s 1000s 100s 10s 1s
    0

    D
    100000s 10000s 1000s 100s 10s 1s
    0
    Solution
    A is smaller than B because A has 0 at hundred thousands place. Each number contains 0 only once, and none of the other numbers has zero at hundred thousands place. Therefore, A will always be smaller than B because A is a 5-digit number, while others, including B, are 6-digit numbers.
  • Question 30
    1 / -0
    Look at the values below:

    a. MV _____ MIV
    b. MMV _____ MMVI
    c. MXVI ______ MXXVI

    Compare these values and use the correct symbols to denote the comparison.
    Solution
    (a):
    MV = 1000 + 5 = 1005
    MIV = 1000 + 4 = 1004

    Therefore,
    MV > MIV

    (b):
    MMV = 1000 + 1000 + 5 = 2005
    MMVI = 1000 + 1000 + 6 = 2006

    Therefore,
    MMV < MMVI

    (c):
    MXVI = 1000 + 10 + 6 = 1016
    MXXVI = 1000 + 10 + 10 + 6 = 1026

    Therefore,
    MXVI < MXXVI

    Hence, option 2 is correct.
