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 - Find the time between 8 and 9 o' clock will the hands of a clock be in the same straight line but not together.

A - 120/11 min to 9

B - 120/11 min past 8

C - 11 min past 8

D - None of these

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?

A - 7:20PM on Tue

B - 6:20PM on Wednesday

C - 7:20 PM on Wed

D - None of these

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?

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 - A clock is begun at twelve. By 10 min. past 5, the hour hand has turned through:

A - 145°

B - 150°

C - 155°

D - 160°

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:

A - 80°

B - 75°

C - 60°

D - 105°

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:

A - 180°

B - 385°/2

C - 195°

D - 395°/2

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 - What number times in a day, are the hands of a check in straight line however in bearing?

A - 22

B - 24

C - 44

D - 48

Answer : A

Explanation

The hands of a check point in inverse headings 11 times in every 12 Hours.
(since somewhere around 5 and 7 they point in inverse headings at 6 o'clock just)
So in a day, the hands point in the inverse headings 22 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

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 picks up 5 sec. in 3 min. was set comfortable am. Toward the evening Of that day, when the watch demonstrated quarter past 4'o clock the Genuine time is:

A - 715/12 min. past 3

B - 4 p.m.

C - 645/11 min. past 3

D - 25/11 min. past 4

Answer : B

Explanation

Time structure 7 a.m. to 4.15 p.m.=9 hrs 15 min=37/4 hrs.
3 min. 5 sec. of this clock=3 min of the right clock.
=> 37/720hrs of this clock =1/2 hrs of the right clock
=> 37/4 hrs of this clock =(1/20*720/37*37/4)hrs of right clock
= 9hrs of the right clock
∴ The right time is 9 hrs after 7 a.m. i.e. 4 p.m.
