The minute hand of a clock overtakes the hour hand at intervals of 65 minutes of correct time. How much does the clock gain or lose in 12 hours?

Solution

After 60 minute rotation the minute hand will make an angle of 30 degree with hour hand.After that let the time required to make an overtake is t minute
in this time angle covered by minute hand = (360/60)t = 6t
similarly angle covered by hour hand = (30/60)t = t/2
so for overtake 6t = 30 + t/2 or t = 60/11 min = 5 min and 5/11 min = 5 min and 300/11 sec = 5 min and 27.273 sec so clock loses 27.273 seconds

(#M40001550) TCS QUESTION latest question Keep an EYE

A toy train produces at least 10 different tunes when it moves around a circular toy track of radius 5 meters at 10 meters per minute. However, the toy train is defective and it now produces only two different tunes at random. What are the odds that the toy train produces 4 consecutive music tunes of the same type?

a) 1 in 16
b) 1 in 4
c) 1 in 8

Solution

only two different tunes are there, so for making 4 consecutive music tunes of the same type, probability = (1/2)(1/2)(1/2)(1/2)*2 = 1/8
last 2 is because of the two case (1) first tune all 4 times (2) second tune all 4 times
but here the question is based on odds, so answer should be (1/8)/[(1-(1/8)] = 1/7
