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

C - (40/11)h minutes past h o' clock

D - (30/11)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 - 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 - Find the angle between the two hands of a clock at 15 minutes past 5 o' clock.

Answer : C

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

Answer : C

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?

Answer : C

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 do the hands of a check agree in a day?

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 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 - At what time somewhere around 4 and 5 o'clock will the hand of a watch point In inverse headings?

A - 45 min. past 4

B - 40 min. past 4

C - 554/11 min. past

D - 100/11 min. past 4

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.
