Q 1 - At what time between 2 and 3 o' clock will the hands of a clock be together?
At 2 o' clock, the hour hand is at 2 and minute hand is at 12
i.e. they are 10 min spaces apart.
The minute hand has to gain 10 minute spaces
over the hour hand to be together.
The minute hand gains 55 mins in 60 mins.
∴ It will gain 10 mins in 60/55 * 10 min
= 120/11 minutes.
Hence the hands will coincide at 120/11 minutes past 2.
Q 2 - At what time between 4 and 5 o' clock will the hands of a clock be at right angle?
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 - 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?
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?
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
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 - The point between the moment hand and the hour hand of a clock At the point when the time is 8.30, is:
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 - How commonly in a day, the clock's hands are straight?
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?
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.
