Q 1 - Find the angle between the hour hand and the minute hand of a clock when the time is 3.25.

A - 30°

B - 50°

C - 95/2°

D - None of these

### 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 - At what time between 4 and 5 o' clock are the hands of a clock 3 minutes apart?

A - 45.09 minutes past 4 o' clock.

B - 35.09 minutes past 4 o' clock.

C - 25.09 minutes past 4 o' clock.

D - 15.09 minutes past 4 o' clock.

### Explanation

```At 4 o' clock, the minute hand is 20 min spaces behind the hour hand.
There are two possible cases for the given scenario.

Case I ? Minute hand is 3 min spaces behind the hour hand.
In this case the minute hand has to gain (20-3) = 17 minutes.
= (60/55) * 17
= (12/11) * 17
= 204/11

∴ The minute hand will be 3 minute apart at 204/11 min or 18.54 min past 4.

Case II ? Minute hand is 3 minutes spaces ahead of the hour hand.
In this case the minute hand has to gain (20+3) = 23 minute spaces.
= (60/55)*23
= (12/11)*23
= 276/11
= 25.09 minutes

∴ The hands will be 3 minute apart at 25.09 minutes past 4 o' clock.```

Q 3 - Find the angle between the two hands of a clock at 15 minutes past 5 o' clock.

A - 30°

B - 35°

C - 67.5°

D - 37.5°

### Explanation

```At 15 minutes past 5 o' clock, the minute hand is at 3
and hour hand is slightly ahead of 5.

In 60 minutes, the hour hand moves ahead by 300
∴ In 15 minutes, the hour hand moves ahead by = (30/60)*15
= 7.5°

Angle between 3 and 5 hour spaces = 60°.
∴ The total angle between the two hands at
15 minutes past 5 o' clock = 60 + 7.5 = 67.5°```

Q 4 - A clock is set comfortable Am. The check loses 16 minutes in 24 hours. What will be the genuine time when the clock shows 10 pm on fourth day?

A - 11 pm

B - 12 pm

C - 11 am

D - 12 pm

### Explanation

```Time from 5am on a day to 10 pm on fourth day= 89 hours
Presently 23hrs. 44min. of this clock= 24 hours of right clock.
∴ 356/15 hrs of this clock= (24*15/356*89) hrs. Of right clock.
= 90 hrs of right clock.
Along these lines, the right time is 11 pm.```

Q 5 - At 3.40, the hour hand and the moment hand of a clock from a point of

A - 120°

B - 125°

C - 130°

D - 135°

### Explanation

```Angle followed by hour hand in 12 hours= 360°
Point followed by hour it in 11/3 hrs. =(360/12*11/3)= 110°
Point followed by moment hand in 60 min. =360°
Point followed by it in 40 min. =(360/60*40) = 240°
∴ Required Angle = (240-110)= 130°```

Q 6 - At what edge the hands of a clock are slanted at 15 min. past 5?

A - 117°/2

B - 64°

C - 135°/2

D - 145°/2

### Explanation

```Angle followed by hour hand in 21/4 hrs.=(360/12*21/4)°315°/2
Edge followed by min. hand in 15 min. =(360/12*15)°= 90°
∴ Required edge = (315/2)°-90°= 135°/2```

Q 7 - How commonly in a day, the clock's hands are straight?

A - 22

B - 24

C - 44

D - 48

### Explanation

```In 12 hours, the hands concur or are in inverse heading 22 times.
∴ In 24 hours, the hands concur or are
in inverse heading 44 Times each day.```

Q 8 - How commonly are the hands of a check at right edge in a day?

A - 22

B - 23

C - 44

D - 48

### Explanation

```In 12 hours, they are at right point 22 times.
∴ In 24 hours , they are at right point 44 times.```

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?

A - 5 min. Past 7

B - 57/11 min. past 7

C - 58/11 min. past 7

D - 60/11 min. past 7

### 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 - At what time somewhere around 5.30 and 6 will the hand of a clock be at right Points?

A - 70/11 min. past 5

B - 80/11 min. past 5

C - 40 min. past 5

D - 45 min. past 5

```At 5 o'clock, the hands are 25 min. space separated.
