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 - Find the angle between the two hands of a clock at 5:30 PM.
Answer : A
Explanation
At 5:30 PM, the minute hand is at 6 and hour hand is past 5 but behind 6. In 60 minutes, the hour hand moves ahead by 30°. ∴ In 30 minutes, hour hour hand moves ahead by = 30*(30/60)° = 15° Angle between 5 and 6 hour spaces = 30°. Hence, angle between the two hands at 5:30 PM = (30 - 15) = 15°.
Q 5 - An exact check demonstrates 8 o'clock in the morning . through what number of degrees will the hour hand pivot when the clock indicates 2 O' check toward the evening?
Answer : D
Explanation
Angle followed by the hour hand in 6 hours = (360/12*6)°= 180°
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°
Q 7 - The reflex edge between the hands of a clock at 10.25 is:
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?
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 - At what time somewhere around 4 and 5 o'clock will the hand of a watch point In inverse headings?
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.
