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 - 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 - 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
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 - 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 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 - 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.
