Q 1 - The two hands of a clock will be together between h and (h+1) o'clock at

A - (60/11)h minutes past h o' clock

B - (50/11)h minutes past h o' clock

### Answer : A

### Explanation

At h o' clock, the minutes hand is 5 h minute spaces behind the hour hand. The minute hand gains 55 min spaces in 60 mins. ∴ The minute hand will gain 5h minute spaces in 60/55 * 5h = 60h/11 minutes. ∴ The two hands will be together between 'h' and 'h+1' o' clock at (60/11)h minutes h o' clock.

Q 2 - At what time between 4 and 5 o' clock will the hands of a clock be at right angle?

### Answer : B

### Explanation

At 4 o' clock, the minute hand is 20 minute spaces behind the hour hand. Now, when the two hands are at right angles, they are fifteen min spaces apart. So, they are at right angles in following two cases. Case I ? When the minute hand is 15 min spaces behind the hour hand. In this case, min hand will have to gain (20-15) = 5 min spaces. = (60/55)*5 = 60/11 ∴ They are at right angle at 60/11 minutes past 4. Case II ? When the minute hand is 15 minute spaces ahead of the hour hand. In this case the minute hand will have to gain (20+15) = 35 min spaces. = (60/55)*35 = 420/11 min ∴ They are at right angles at 420/11 min past 4.

Q 3 - The minute hand of a clock overtakes the hour hand at interval of 65 minutes of the correct time. How much a day does the clock gain or lose?

### Answer : C

### Explanation

In a correct clock, the minute hand gains 55 min spaces over the hour hand in 60 minutes. To be together again, the minute hand must gain 60 minutes over the hour hand. 55 min are gained in 60 min 60 min are gained in (60/55)*60 = 720/11 But they are together after 65 min. ∴Gain in 65 min = (720/11 ? 65) = 5/11 Gain in 24 hours = [5/11 * (60*24)/65] min = 440/43 min = 10.23 minutes. ∴The clock gains 10.23 minutes in 24 hours.

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 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 somewhere around 7 and 8 o'clock will the hands of a be in the Same straight line at the same time, not together?

### Answer : D

### Explanation

When the check's hands are in the same straight line however not together. they are 30 moment spaces separated. At 7 o' clock, they are 25 min. space separated. ∴ Minute hand will need to increase just 5 min. spaces. 55 min. spaces are picked up in 60 min. 5 min. spaces are picked up in (60/55*5)min=60/11 min. ∴ Required time=60/11 min. past 7.

Q 10 - A watch which pick up consistently is 2 minutes moderate at twelve on Monday What's more, is 4 min.48 sec quick at 2 p.m. on the next Monday. At the point when Is it true that it was right?

### Answer : B

### Explanation

Time structure 12 p.m. on Monday to 2 p.m. on the accompanying Monday =7 days 2 hours =170 hours. ∴ The watch gains(2+24/5)min. on the other hand 34/5 min. in 170 hrs. Now,34/5 min. are picked up in 170 hrs. ∴ 2 min. are picked up in (170(5/34*2) hrs=50 hrs. Along these lines, the watch is right 2 days 2 hour after 12 p.m. on Monday i.e.it will be right at 2 p.m. on Wednesday.
