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
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.
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 loses 16 minutes in 24 hours. What will be the genuine time when the clock shows 10 pm on fourth day?
Answer : A
Explanation
Time from 5am on a day to 10 pm on fourth day= 89 hours Presently 23hrs. 44min. of this clock= 24 hours of right clock. ∴ 356/15 hrs of this clock= (24*15/356*89) hrs. Of right clock. = 90 hrs of right clock. Along these lines, the right time is 11 pm.
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 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
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?
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 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.
