Q 1 - At what time between 2 and 3 o' clock will the hands of a clock be together?
Answer : A
Explanation
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 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.
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 - 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?
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?
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:
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 edge between the moment hand and the hour hand of a clock when the time is 4.20, is:
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°
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 - What number times in a day, are the hands of a check in straight line however in bearing?
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 somewhere around 9 and 10 o'clock will the hands of a watch be together?
Answer : C
Explanation
To be as one somewhere around 9 and 10 o'clock, the moment hand needs to pick up 45 min. spaces. 55 min. space are picked up in 60 min. 45 min. space are picked up in (60/55*45) min. or 540/11 min. ∴ The hands are as one at 540/11 min. past 9.
Q 10 - At what time somewhere around 5.30 and 6 will the hand of a clock be at right Points?
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.
