How much does a watch gain or lose per day if its hands coincide every 65 minutes?
1440/22 = 65 and 5/11 minutes. => every 65 and 5/11 min, they coincide. Now the clock in question coincide every 64 minutes; therefore 24 hours in your clock means 64*22 minutes or 1408 minutes. So your clock should lose 1440-1408=32 minutes.
How much does a watch lose per day if its hands coincide every 66 minutes?
When the hands of clock will meet again, the minute hand will cover 360° more than hour hand. It will happen after minutes. Since hands of the clock are coinciding after 66 minutes so the clock is losing 6/11 minutes in 66 minutes.
How many times watch hands coincide in a day?
The hands of a clock coincide 11 times in every 12 hours (Since between 11 and 1, they coincide only once, i.e., at 12 o’clock). The hands overlap about every 65 minutes, not every 60 minutes. The hands coincide 22 times in a day.
How much does watch lose per day?

How much time does a watch lose per day?
How much does a watch lose per day, if its hands coincide every 64 minutes? In a correct clock, in 60 minutes, minute hand gains 55 minute spaces over the hour hand. In the given watch, hands coincide every 64 minutes. i.e., in the given watch, in 64 minutes, minute hand gains 60 minute spaces over the hour hand.
What angle does the minute hand of a clock turn in 5 minutes?
The minute hand sweeps an angle of 30 degrees in 5 mins…
What is the acute angle between the hands of a clock at 15 minutes past 5?
Aptitude :: Clock – Discussion
At what angle the hands of a clock are inclined at 15 minutes past 5? = 90°.
What is the angle between the hour hand and the minute hand of a clock when the time is 3 25?
Explanation: As, the hour hand covers 360 degrees in 12 hrs. In the clock the time is 3.25 = 3 hrs 25 min = 41/12 hrs. So, the angle traced by hour hand = (360/12 x 41/12) degrees = 205 degrees.
How many times does a clock have 90 degrees?
If you switch to a rotating coordinate system in which the hour hand stands still, then the minute hand makes only 11 revolutions, and so it is at right angles with the hour hand 22 times. In a 24 hour day you get 2×22=44.
How many times will minute hand and hour hand coincide in one day?
Also, the hour and minute hand coincide only once between 11 and 1 o’clock i.e. at 12 o’clock. So, from both the above statements we can say that the two hands coincide exactly 11 times in a 12 hour span. times. So, the number of times the two hands coincide in a day is 22 times.
How many times will a clock strike in 24 hours if it strikes only at the hours?
GIVEN : The clock strikes once at 1 o’clock,twice at 2 o’clock and so on. [1 day = 24 hours] clock has 12 hours so we have to multiply the series by 2 to make it 24 hours. Hence, the clock will strike 156 times in a day.
At what time between 9 and 10 will the hands of a watch be together?
Explanation: To be together between 9 and 10 o’clock, the minute hand has to gain 45 min. spaces. 55 min.
What is the time between 7 and 8 o clock?
At what time between 7 and 8 o’clock will the hands of a clock be in the same straight line but, not together? Explanation: When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart. At 7 o’clock, they are 25 min.
At what time between 5 and 6 will the hands of the clock coincide?
Q10. At what time between 5 and 6 pm will the hands of a clock be coincident? Between 5 and 6 pm, hands of a clock will be together at 5 6 (12/11) min past 5 i.e. 360/11 = 32(8/11) min past 5.
