  • Question 1
    1 / -0
    What is the value of MMMDCCLX - MMMDCLVI?
    Solution
    I = 1
    V = 5
    X = 10
    L = 50
    C = 100
    D = 500
    M = 1000
    So, MMMDCCLX - MMMDCLVI= 3760 - 3656 = 104 = CIV

    Solution
    Statement 1:
    Total winning amount = Rs. 7,26,416
    Number of winners = 8
    Each winner will get = = Rs. 90,802
    Statement 2:
    Total amount of money = Rs. 159600
    Number of family = 14
    Amount of money per family = 159600 ÷ 14 = Rs. 11400

  • Question 10
    1 / -0

    Find the value of .
    Solution
    Let 2 fruits be orange and guava (as seen in figure)
    Given that:
    2 oranges + 1 guava = 60 ... Equation 1
    1 orange + 1 guava = 45 ... Equation 2

    From equation 2 we can calculate guava as
    1 guava = 45 - 1 orange

    Now, put the value of 1 guava in equation 1. i.e.
    2 oranges + (45 - 1 orange) = 60

    2 oranges - 1 orange + 45 = 60
    1 orange = 60 - 45 = 15

    Then, we can find the value of 1 guava from equation 2 as
    1 orange + 1 guava = 45
    15 + 1 guava = 45
    1 guava = 45 - 15 = 30

    Therefore, the value of 1 guava is 30.

    X = 1559 + 69 = 1628

    According to 1st line of question we have,
    814 a number = 1628
    Now, required number =
    Hence, option (2) is correct.

    What is the total number of flowers used?
    Solution
    Flowers for each door = 895
    For 2 doors = 2 x 895
    Flowers used for each edge = 1456
    For 4 edges = 4 x 1456 = 5824
    For centre = 5461
    Total flowers required = 2 x 895 + 5824 + 5461 =1790 + 5824 + 5461 = 13075 flowers

    In a factory there are 2 types of machines A and B. A can produce 8550 units, which is 360 more than produced by B in a day. Each of 30 units are packed in a big box. How many big boxes will be there if both the machines are used for 9 days?
    Solution
    Number of units machine A produces daily = 8550
    So, number of units produced by machine B = 8550 - 360 = 8190 per day.
    Hence, total units produced by both the machines daily = 8550 + 8190 = 16740.
    Number of units produced in 9 days = 9 x 16740 = 150660
    Number of units in 1 box = 30
    Number of boxes = 150660 ÷ 30 = 5022
    Hence, option (2) is correct.
  • Question 29
    1 / -0
    Jack has 45895 stickers with him. He gave 15630 to his friend and another 20635 to his brother and after that he buys 2135 new stickers. What is the number of stickers that he has now?
    Solution
    Number of stickers = 45895
    Total stickers that he gave to his friend and brother = 15630 + 20635 = 36265
    Number of stickers he buys = 2135
    Number of stickers left = 45895 - 36265 + 2135 = 11765
    Hence, option (2) is correct.
  • Question 30
    1 / -0
    Complete the addition square by finding the missing numbers. Find (P+Q)-(R-S).

    + 13,256 5,693
    15,236 P Q
    9,546 R S
    Solution
    From, the given table,
    P = 15, 236 + 13, 256 = 28492
    Q = 15, 236 + 5, 693 = 20929
    R = 9, 546 + 13, 256 = 22802
    S = 9, 546 + 5, 693 = 15239
    P + Q = 28492 + 20929 = 49421
    R - S = 22802 - 15239 = 7563
    So, (P + Q) - (R - S) = 49421 - 7563 = 41858
    Hence, option (1) is correct.
