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 - A clock is set comfortable Am. The check picks up 10 minutes in 24 hours. What will be the genuine time when the clock shows 1 pm on the taking after?
Answer : B
Explanation
Time from 8 Am on a day to 1p.m on the accompanying day= 29 hrs. 24 hours 10 min. of this clock = 24 hrs. Of the right clock. 145/6 hrs. of this clock= 24 hrs of the right clock. 29 hrs. of this clock = (24*6/145*29)hrs of the right clock. = 28 hrs 48 min. of right clock. ∴The right time is 28 hrs 48 min. after 8 am This is 48 min. past. 12.
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 edge between the moment hand and the hour hand of a clock when the time is 4.20, is:
Answer : B
Explanation
Angle followed by hour hand in 13/3 hrs. =(360/12*13/3)°= 130° Point followed by min. hand in 20 min. = (360/60*20)°= 120° ∴ Required point = (130-120)°= 10°
Answer : C
Explanation
The hands of a check match 11 times in at regular intervals. ∴ The hands concur 22 times in a day.
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 somewhere around 9 and 10 o'clock will the hands of a watch be together?
Answer : C
Explanation
To be as one somewhere around 9 and 10 o'clock, the moment hand needs to pick up 45 min. spaces. 55 min. space are picked up in 60 min. 45 min. space are picked up in (60/55*45) min. or 540/11 min. ∴ The hands are as one at 540/11 min. past 9.
Q 10 - At what time somewhere around 4 and 5 o'clock will the hand of a watch point In inverse headings?
Answer : D
Explanation
At 4 o' clock, the watch's hands are 20 min. space Separated. To be in inverse directions, they must be 30 min. space Separated. ∴ Minute hand will need to pick up 50 min. space. 55 min. space are picked up in 60 min. 50 min. space are picked up in (60/11*50) min. on the other hand 100/11 min. ∴ Required time=100/11 min. past 4.
