Questions and Answers

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

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 - 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.

Answer : C

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 - 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?

A - 10.20 minutes in 24 hours

B - 10.25 minutes in 24 hours

C - 10.23 minutes in 24 hours

D - None of these

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?

A - 58 min. past. 12

B - 48 min. past. 12

C - 38 min. past. 12

D - 28 min. past. 12

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 - An exact check demonstrates 8 o'clock in the morning . through what number of degrees will the hour hand pivot when the clock indicates 2 O' check toward the evening?

A - 144°

B - 150°

C - 168°

D - 180°

Answer : D

Explanation

Angle followed by the hour hand in 6 hours
= (360/12*6)°= 180°

Q 6 - The edge between the moment hand and the hour hand of a clock when the time is 4.20, is:

A - 0°

B - 10°

C - 5°

D - 20°

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°

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

A - 22

B - 24

C - 44

D - 48

Answer : C

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

Answer : C

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, in moment, between 3 o'clock and 4 o'clock, both are unnecessary will match one another?

A - 56/11 past 3

B - 136/11 past 3

C - 147/11 past 3

D - 180/11 past 3

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?

A - 70/11 min. past 5

B - 80/11 min. past 5

C - 40 min. past 5

D - 45 min. past 5

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.
