Q 1 - Find the angle between the hour hand and the minute hand of a clock when the time is 3.25.
Answer : C
Explanation
Angle traced by the hour hand in 12 hours = 360° Angle traced by it 3 hr 25 minutes i.e 41/12 hrs = 360°/12 * 41/12 = 105°/2 Similarly, angle traced by min hand in 60 mins = 360° Angle traced by it in 25 mins = 3600/60 * 25 = 150° ∴ Angle between hour hand and minute hand = 150° ? 105°/2 = 95°/2
Q 2 - Find the time between 8 and 9 o' clock will the hands of a clock be in the same straight line but not together.
Answer : B
Explanation
At 8 o? clock, the two hands are 20 min spaces apart. To be in the same straight line but not together, they will be 30 min spaces apart. So, the minute hand will have to gain (30-20) = 10 minute spaces over the hour hand. = 60/55 * 10 = 120/11 ∴The hands will be in the same straight line but not together at 120 min past 8.
Q 3 - A watch which gains uniformly in 5 min slows at 8 o? clock in the morning on Sunday and it is 5 min 48 sec fast at 8 pm on the following Sunday. When was it correct?
Answer : C
Explanation
Time from 8 am on Sunday to 8 pm on following Sunday = 7 days 12 hours = 180 hours ∴ The watch gains (5 + 29/5) min or 54/5 min in 180 hours. Now 54/5 minutes are gained in 180 hours. ∴ 5 minutes are gained in [180*(5/54)*5] hour = 83 hr 20 min = 3 days 11 hours 20 minutes Watch is correct 3 days 11 hours 20 minutes after 8 AM of Sunday i.e. 7:20PM on Wednesday.
Q 4 - Find the angle between the two hands of a clock at 5:30 PM.
Answer : A
Explanation
At 5:30 PM, the minute hand is at 6 and hour hand is past 5 but behind 6. In 60 minutes, the hour hand moves ahead by 30°. ∴ In 30 minutes, hour hour hand moves ahead by = 30*(30/60)° = 15° Angle between 5 and 6 hour spaces = 30°. Hence, angle between the two hands at 5:30 PM = (30 - 15) = 15°.
Q 5 - A clock is begun at twelve. By 10 min. past 5, the hour hand has turned through:
Answer : C
Explanation
Angle followed by hour hand in 12 hrs =360° Point followed by hour hand in 5 hrs 10 min. =31/6 = (360/12*31/6)°= 155°
Q 6 - The point between the moment hand and the hour hand of a clock At the point when the time is 8.30, is:
Answer : B
Explanation
Angle followed by hour hand in 17/2hrs= (360/12*17/2)°= 255° Point followed by min. hand in 30 min. = (360/60*30)°= 180° ∴ Required Angle = (255-180)°=75°
Q 7 - The reflex edge between the hands of a clock at 10.25 is:
Answer : D
Explanation
Angle followed by hour hand in 125/12 hrs.=(360/12*125/12)°=625°/2 Edge followed by min. hand in 25 min. =(360/60*25°)= 150° Reflex angle= 360°-(625/2-150)°= 360°-325°/2 = 395°/2
Q 8 - How much does a watch lose every day, if its hands agree each 64 Min?
Answer : B
Explanation
55 min. spaces are secured in 60 min. 60 min. spaces are secured in (60/55*60) min. = 720/11 min. Misfortune in 64 min. = (720/11-64)= 16/11 min. Misfortune in 24 hrs =(16/11*1/64 *24*60)min.=400/11 min.
Q 9 - At what time, in moment, between 3 o'clock and 4 o'clock, both are unnecessary will match one another?
Answer : D
Explanation
At 3 o'clock ,the moment hand is 15 min. spaces a section Structure the hour hand. To be coincident, it must pick up 15 min. spaces. 55 min. are picked up in 60 min. 15 min. are picked up in (60/55*15)min.=180/11 min. ∴ The hands are correspondent at 180/11 min. past 3.
Q 10 - At what time somewhere around 5.30 and 6 will the hand of a clock be at right Points?
Answer : B
Explanation
At 5 o'clock, the hands are 25 min. space separated. To be at right edges and that too somewhere around 5.30 and 6,the moment hand needs to increase (25+15)=40 min. spaces. 55 min. space are gained in 60 min. 40 min. space are picked up in(60/55*40)min.=80/11 min. ∴ Required time =80/11 min. past 5.
