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 - Find the time between 8 and 9 o' clock will the hands of a clock be in the same straight line but not together.
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 - 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?
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?
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 - The point between the moment hand and the hour hand of a clock At the point when the time is 8.30, is:
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°
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 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?
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:
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.
