    In the given figure, there are 45 squares. Explanation: Total number of columns in Big Square = 4 Total number of rows in Big Square = 4 So, rows = columns Formula = 12+22+32+42 = 1 + 4 + 9 + 16 = 30 Now, number of small squares = 3 each with 5 squares = 3x5 = 15 Hence, total number of suares = 30 +Read more

    In the given figure, there are 45 squares.

    Explanation:

    Total number of columns in Big Square = 4

    Total number of rows in Big Square = 4

    So, rows = columns

    Formula = 12+22+32+42

    = 1 + 4 + 9 + 16

    = 30

    Now, number of small squares = 3 each with 5 squares = 3×5 = 15

    Hence, total number of suares = 30 + 15 = 45

    The time at which the hands of the clock will be in 180 degrees between 9 and 10 'o'clock is 180/11 min past 9.

    The time at which the hands of the clock will be in 180 degrees between 9 and 10 ‘o’clock is 180/11 min past 9.

    Explanation:

    Formula to find the time of a clock when an angle and hour is mentioned is A = [30H – (11/2) x minutes]

    Here,

    • A = Given Angle
    • H = Initial position of the hour hand

    Now, using the formula, we get –

    ==> 180 = 30 x 9 – 11/2 m

    ==> 180 + 11/2 m = 270

    ==> 11/2 m = 270 – 180 = 90

    ==> 11m = 90 x 2

    ==> m = 180/11

    Hence, at 180/11 minutes past 9, the hands of a clock will be in 180 degrees stretch between 9 ‘o clock and 10 ‘o clock.

    75 degrees is the angle between the minute hand and the hour hand of a clock when the time is 8:30.

    Explanation:

    Formula

    A = 30H – (11/2) M

    • A is the Required Angle
    • H is the position of the Hour hand
    • M is the minutes

    A = 30 x 8 – (11/2) x 30

    A = 240 – 165

    A = 75

    Hence, the two hands of a clock will be inclined at an angle of 75 degrees when the time is 8 hours 30 minutes.

    The hour hand on the bottom clock should point to 8.

    Explanation:

    When you keenly observe the given figure (Clockwise) from the top clock,

    • The minute hand is moving clockwise 15 minutes in each figure
    • The hour hand is moving anti-clockwise 2 hours in each figure

    So, as the second figure shows the hour hand on 10, the next clock figure should have its hour hand pointing towards 8.

    The reflex angle between the hands of a clock at 10 hours 25 minutes is 197 1/2 degrees.

    The reflex angle between the hands of a clock at 10 hours 25 minutes is 197 1/2 degrees.

    Explanation:

    FORMULA

    A = 30H – (11/2)M

    • A is the required angle
    • H is the position of the hour hand
    • M is the minutes

    A = 30 x 10 – (11/2) x 25

    A = 300 – 275/2

    A = (600 – 275)/2

    A = 325/2

    A = 162.5

    The Reflex Angle of 162.5 is 360 – 162.5 = 197.5 degrees or 197 1/2 degrees

    The hour hand in a clock moves around 2 times in a day i.e., it completes one rotation every 12 hours.

    In 12 hours, the hour hand makes one rotation, and the minute hand makes 12 rotations. So the minute hand passes (coincides with) the hour hand 11 times in 12 hours or 22 times in 24 hours.

    Height of the table is 150 cms.

    Explanation:

    From the given figure,

    Consider the heights of Cat as C, Tortoise as D, & Table as T.

    It can be observed from Figure 1 that C + T – D = 170 cms

    and from Figure 2, it is clear that D + T – C = 130 cms

    Consider these two statements and add them –

    We will get, T + T = 170 + 130 cms

    So, 2T = 300 cms

    T= 150 cms.

    Hence, the height of the table is 150 cms.

    The clock ticks six o’clock in 26 minutes.

    Explanation:

    As per the given data, the clock has already ticked 3 o’clock. So, let’s consider there are “M” minutes until it’s six o’clock in that clock.

    When you observe, there are 180 minutes between 3 o’clock and 6 o’clock. So, it is clear that 180 – M is the number of minutes past 3 o’clock. And also, according to the question, 50 minutes ago it was four times the minutes past 3 o’clock.

    So, we need to consider 180 – 50 = 130 minutes instead of 180 minutes as it was already past 50 minutes.

    Now, the required minutes is 4 times. So, it will be 4 x M.

    ==> 4M = 130 – M

    ==> 4M + M = 130

    ==> 5M = 130

    ==> M = 26

    Hence, 26 minutes are left until the clock ticks six o’clock

    Between 3 o’clock and 4 o’clock, the needles will coincide with each other at 16 4/11 minutes past 3.

    Explanation:

    FORMULA

    A = 30H – (11/2)T

    1. A is the given angle
    2. H is the initial position of the hour hand
    3. T is the required time

    At the point of coincidence, the angle between the two needles will be ZERO degrees. So,

    0 = 30 x 3 – (11/2)T

    (11/2)T = 90

    11T = 180

    T = 180/11 = 16 4/11 minutes past 3

    Hence, the minute hand and the hour hand will coincide at 16 4/11 minutes past 3
