  1. Question 1 of 24
    1. Question

    In 16 minutes, the minute hand gains over the hour hand by:

    Hint

    The minute hand covers 6° in one minute and the hour hand covers 0.5° in one minute.
    Thus, minute hand will gain (6–0.5)=5.5° over the hour hand in one minute.

    In  16 minutes, the minute hand gains (16×5.5)=88° over the hour hand.

  2. Question 2 of 24
    2. Question

    If the two hands in a clock are 3 minutes divisions apart, then the angle between them is:

    Hint

    In a clock, each minute makes 6°
    So, 3 minutes will make 6×3=18°

  3. Question 3 of 24
    3. Question

    What will be the angle between hands of a clock at 2:30?

    Hint

    The minute hand covers 6° in one minute and the hour hand covers 0.5° in one minute.
    Thus, the minute hand will gain (6–0.5)=5.5° over the hour hand in one minute.

    At 2’o Clock, Minute Hand will be 10×6=60° behind the Hour Hand.
    In 30 minutes, Minute Hand will gain 5.5°×30=165°.
    The angle between Hour Hand and Minute Hand =165–60=105°.

  4. Question 4 of 24
    4. Question

    What is the angle between the 2 hands of the clock at 8:24 pm?

    Hint

    The minute hand covers 6° in one minute and the hour hand covers 0.5° in one minute.
    Thus, the minute hand will gain (6–0.5)=5.5° over the hour hand in one minute.

    At 8:00 pm, the angle between Minute Hand and  Hour Hand will be 40×6=240°.
    In 24 minutes, Minute Hand will gain 24×5.5=132°.
    Required angle =240–132=108°.

  5. Question 5 of 24
    5. Question

    At what angle the hands of a clock are inclined at 15 minutes past 5?

    Hint

    The minute hand covers 6° in one minute and the hour hand covers 0.5° in one minute.
    Thus, the minute hand will gain (6–0.5)=5.5° over the hour hand in one minute.

    At 5:00 pm, the angle between Minute Hand and Hour Hand will be 25×6=150°.
    In 15 minutes, Minute Hand will gain 15×5.5=82.5°.
    Required angle =150–82.5=67.5°.

  6. Question 6 of 24
    6. Question

    Find the angle between the hour hand and the minute hand of a clock when the time is 3:25.

    Hint

    The minute hand covers 6° in one minute and the hour hand covers 0.5° in one minute.
    Thus, the minute hand will gain (6–0.5)=5.5° over the hour hand in one minute.

    At 3 o’clock, the angle between Minute Hand and Hour Hand will be 15×6=90°.
    In 25 minutes, Minute Hand will gain 25×5.5=137.5°.
    Required angle =137.5–90=47.5°.

  7. Question 7 of 24
    7. Question

    If a clock strikes 12 in 33 seconds, it will strike 6 in how many seconds?

    Hint

    In order to strike 12, there are 11 intervals of equal time
    =33÷3=11 seconds each
    Therefore, to strike 6 it has 5 equal intervals,
    it requires 5×3=15 seconds

  8. Question 8 of 24
    8. Question

    At what time between 7 and 8 o’clock will the hands of a clock be in the same straight line but, not together?

    Hint

    When the hands of the clock are in the same straight line but not together, they are 30 minutes space apart.

    At 7 o’clock, they are a 25 minutes space apart.
    So, the minute hand will have to gain only 5 minutes space.

    Minute hand gains 55 minutes space in 60 minutes.

    5 minutes space will gain in:

  17. Question 17 of 24
    17. Question

    A clock is set right at 5 am The clock loses 16 minutes in 24 hours. What will be the true time when the clock indicates 10 pm on the 4th day?

    Hint

    Time from 5 am on a day to 10 pm on the 4th day is 89 hours.
    Now, 23 hours 44 minutes of this clock are the same as 24 hours of the correct clock.
    i.e., ³⁵⁶⁄₁₅ hours of this clock are the same as 24 hours of the correct clock.
    Thus, 89 hours of this clock are the same as:

    clock-calendar-15540.pnghours of the correct clock.
    = 90 hrs of the correct clock.
    So, the correct time is 11 pm.

  18. Question 18 of 24
    18. Question

    A watch which gains 5 seconds in 3 minutes was set right at 7 am. In the afternoon of the same day, when the watch indicated quarter past 4 o’clock, the true time is:

    Hint

    Time from 7 am to quarter past 4
    = 9 hours 15 minutes = 555 minutes
    Now, (3 min +5 sec) = 37⁄12 minutes of this watch are the same as 3 minutes of the correct watch.
    555 minutes of this watch will be the same as:
    clock-calendar-15534.pngminutes of the correct watch.
    = 9 hours of the correct watch.
    The correct time is 9 hours after 7 am i.e., 4 pm

  19. Question 19 of 24
    19. Question

    A clock gains 15 minutes per day. It is set right at 12 noon. What time will it show at 4.00 am, the next day?

    Hint

    Time from 12 noon to 4.00 am, the next day
    = 16 hours
    The clock gains 15 minutes in 24 hours.
    Therefore, in 16 hours, it will gain 10 minutes.
    Hence, the time shown by the clock will be 4.10 am.

  20. Question 20 of 24
    20. Question

    A clock is set right at 1 pm. If it gains one minute in an hour, then what is the true time when the clock indicates 6 pm in the same day?

    Hint

    Time interval indicated by the incorrect clock from 1 pm to 6 pm
    = 5 hours = 300 minutes
    Now, 61 minutes of this watch are the same as 60 minutes of the correct watch.
    300 minutes of this watch will be the same as:
    (60/61)×300 minutes of the correct watch.
    = 456⁄61 hours of the correct watch.
    The correct time is 456⁄61 hours after 1 pm
    Thus, the true-time = 555⁄61 minutes past 5

  21. Question 21 of 24
    21. Question

    Two clocks were set right at noon on Sunday. One gains 2 min and the other loses 3 min in 24 hours. What will be the true time when the first clock indicates 3 pm on Wednesday?

    Hint

    Time from noon on Sunday to 3 pm on Wednesday is 75 hours.
    24 hours 2 minutes of the first clock are the same as 24 hours of the correct one.
    1 hour of the first clock =24×(30/721) hours of correct one.
    75 hours of the first clock =24×30×(75/721) hours of the correct one.
    = 54000/721 hours = 74 hours 53.7 minutes.
    Hence the answer is 2:54 pm.

  22. Question 22 of 24
    22. Question

    In a watch, the minute hand crosses the hour hand for the third time exactly after every 3 hr 18 min 15 sec of watch time. What is the time gained or lost by this watch in one day?

    Hint

    Minute hand gains 55 minutes space in 60 minutes.

    In a watch that is running correctly, the minute hand should cross the hour hand once in every:
    60×(60/55) minutes.
    So they should ideally cross 3 times once in:
    3×60×(60/55) minutes =196.36 minutes.

    But in the watch under consideration, they meet after every 3hr, 18 min and 15 seconds, i.e. 198.25 minutes.
    Thus, the watch is actually losing time (as it is slower than the normal watch).

    Hence 1 day (1440 min) of this watch will be:
    1440×(196.36/198.25) = 1426.27 minutes.

    Hence the amount of time lost the watch in one day:
    =1440–1426.27=13.73 minutes
    i.e., 13 min and 50s (approx).

  23. Question 23 of 24
    23. Question

    A clock gains 5 minutes in 24 hours. It was set right at 10 am on Monday. What will be the true time when the clock indicates 10:30 am on the next Sunday?

    Hint

    Time between 10 am on Monday to 10:30 am on Sunday
    = 6 days and ½ hrs = 144.5 hrs.

    24 hr + 5 min = 289/12 hours of incorrect clock = 24 hours of correct time.
    So, 144.5 hours of the incorrect clock
    = 144.5×24/(289/12) hours of the correct time
    = 144 hours i.e., the true time is 10 am on Sunday.

  24. Question 24 of 24
    24. Question

    A watch which gains uniformly is 2 minutes slow at noon on Monday and is 4 min. 48 sec. fast at 2 pm on the following Monday. When was it correct?

    Hint

    Time from 12 pm on Monday to 2 pm on the following Monday
    = 7 days 2 hours = 170 hours.

    The watch gains
    clock-calendar-15322.png clock-calendar-15316.png
    Now, 34/5 minutes are gained in 170 hrs.
    So, 2 minutes are gained in
    clock-calendar-15304.png
    Watch is correct 2 days 2 hrs. after 12 pm on Monday i.e., it will be correct at 2 pm on Wednesday.
