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 - 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 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

Q 6 - At what edge the hands of a clock are slanted at 15 min. past 5?
Answer : C
Explanation
Angle followed by hour hand in 21/4 hrs.=(360/12*21/4)°315°/2 Edge followed by min. hand in 15 min. =(360/12*15)°= 90° ∴ Required edge = (315/2)°-90°= 135°/2
Answer : C
Explanation
The hands of a check match 11 times in at regular intervals. ∴ The hands concur 22 times in a day.
Answer : C
Explanation
In 12 hours, they are at right point 22 times. ∴ In 24 hours , they are at right point 44 times.
Q 9 - At what somewhere around 9 and 10 o'clock will the hands of a watch be together?

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
