In the clock the time is 3.25 = 3 hrs 25 min = 41/12 hrs. So, the angle traced by hour hand = (360/12 x 41/12) degrees = 205 degrees. The minute hand covers 360 degrees in 60 minutes. So, the angle is traced by minute hand in 25 min = (360/60 x 25) degrees = 150 degrees. Hence, the required angle of the clock = (150- 205/2) degrees = 95/2 degrees.Question 2What is correct time and day of Ram's magical watch, which gains uniformly 300 seconds slow at time 08:00 on Sunday and 348 fast at 20;00 on following Sunday. 21 min past 7 pm and Wednesday20 min past 7 pm and Thursday21 min past 7 pm and Thursday20 min past 7 pm and WednesdayClocks Discuss itQuestion 2-Explanation: The given time from 8:00 am on Sunday to 8 pm on following Sunday = 7 days 12 hrs = 180 hrs. So, the clock gains = (5 + 29/5)min = 54/5 min in 180 hrs. Hence, 5 min are gained in (180 x 5/54 x 5)hrs = 83 hrs 20 min = 3 days 11 hrs 20 min. The clock is correct 3 days 11 hrs 20 min after 8 am of Sunday. So, the correct time and day will be 20 min past 7 pm on Wednesday.Question 3On the birthday of Sam, Param gave him an alarm clock, now Sam sets alarm at 5 am, and Sam notices that:The clock loses 960 seconds in last one day. Effectively, the clock indicates 10:00 pm on the 4th day. Find out the original time of the clock:9 pm10 pm11 pm08 pmClocks Discuss itQuestion 3-Explanation: From the given information the time from 5 am on a day to 10 pm on the 4th day is 89 hrs. So, 23 hrs 44 min of this clock = 24 hrs of correct clock. Hence, 356/15 hrs of this clock = 24 hrs of correct clock. 89 hrs of the clock = (24 x 15/356 x 89)hrs of correct clock = 90 hrs of correct clock. Hence, the original time will be 11 pm.Question 4Find the original time of clock if:The time of a clock is 08:00,The clock gains 600 seconds, in one day.The time of the clock is 1pm on the following day.48 minutes past 1247 minutes past 1048 minutes past 1148 minutes past 11Clocks Discuss itQuestion 4-Explanation: From 8 am on a day to 1 pm on the following day will be 29 hrs. So, the clock gains 10 min in 24 hours = 24 hrs of the correct time. Hence, 145/6 hrs of the clock = 24 hrs of the correct clock. 29 hrs of the clock = (24 x 6/145 x 24)hrs of the correct clock = 28 hrs 48 min of the correct clock. The correct time = 28 hrs 48 min after 8 am. Hence, the original time is 48 minutes past 12.Question 5At the time of 15:40 in clock, what is the angle between hour hand and minute hand.120 degrees135 degrees140 degrees130 degreesClocks Discuss itQuestion 5-Explanation: The time is same as 03:40The hour hand covers the angle 360 degrees in 12 hrs. So, the angle is covered by it in 11/3 hrs = (360/2 x 11/3) degrees = 110 degrees . The minute hand covers the angle in 360 degrees in 60 min. So, the angle is covered by it in 40 min = (360/60 x 40) degrees = 240 degrees . Hence, the required angle made by both hands = (240 - 110) degrees = 130 degrees .Question 6A clock shows 08:00. When it is 14:00, by what degree the hour hand rotates?145º160º180º175ºClocks Discuss itQuestion 6-Explanation: For 6 hrs duration hrs hand covered 6 hrs out of 12 hrsWhen hrs hand covers 12 hrs it rotates for 360 degree----------------------------6 --------------------- = (360/12)*6 = 180 degreesQuestion 7A clock shows 10:00. When time is 16:00, by what degree the hour hand rotates?140º152º175º180ºClocks Discuss itQuestion 7-Explanation: For 6 hrs duration hrs hand covered 6 hrs out of 12 hrs When hrs hand covers 12 hrs it rotates for 360 degree ----------------------------6 --------------------- = 360/12)*6 = 180 degreesQuestion 8A clock shows 10:00. When time is 22:00, by what degree the hour hand rotates?180175240360Clocks Discuss itQuestion 8-Explanation: For 6 hrs duration hrs hand covered 12 hrs out of 12 hrs When hrs hand covers 12 hrs it rotates for 360 degree ----------------------------12 --------------------- =(360/12)*12 = 360 degreesQuestion 9A clock shows 10:00 AM. What time it will be showing, if hrs hand rotates for 180 degrees?1:00 PM6:00 PM4:00 PM10:00 PMClocks Discuss itQuestion 9-Explanation: When hrs hand rotates for 360 degree it covers 12 hrs --------------------------------- 180 --------------------- 6 hrs So the time will be: 10:00 AM + 6 hrs = 4:00 PMQuestion 10A clock shows 06:00 AM. What time it will be showing, if hrs hand rotates for 360 degrees?4:00 AM of next day06:00 PM04:00 PM10:00 PMClocks Discuss itQuestion 10-Explanation: When hrs hand rotates for 360 degree it covers 12 hrs --------------------------------- 360 --------------------- 12 hrs So the time will be: 06:00 AM + 12 hrs = 06:00 PM 12 There are 19 questions to complete.You have completedquestionsquestionYour accuracy isCorrectWrongPartial-CreditYou have not finished your quiz.
