In all competitive exams the problems on clocks are asking. Analog clock is considered as circle. The total angle formed by a circle is 360 0 Now we need to find out the angle between the hour and minute hand. Now we need to calculate the angle of hour  and minute hand by  considering the reference position as number 12. Angle of  minute and hour hand is calculated from number 12 in clock. Angle formed by a circular clock 360 0 Angle of minute and hour hand calculated from Number 12 Time taken by minute  hand for  one revolution 360 0 =60min                             Angle formed by minute hand in I min 1min =6 0 Time taken by hour hand in one revolution 360 0 = 12 hours Angle formed by hour hand in 1 hour 30 0 = 1 hour                           Angle between hour and minute hand at 3 45 Convert 3Hr45Min into hours =3+(45/60) =3+(3/4) =(12+3)/4 =15/4Hrs

Fibonacci numbers every number after the first two is the sum of the two before numbers. Fibonacci sequence is started from 0. The following table describes the how to write the Fibonacci numbers . Fibonacci sequence: 0,1,1,2,3,5,8…..

In this problem we see what is angle between hands of a clock when the time is 2 45  Analog clock is considered as circle. The total angle formed by a circle is 360 0 Now we need to find out the angle between the hour and minute hand. Now we need to calculate the angle of hour  and minute hand by  considering the reference position as number 12. Angle of  minute and hour hand is calculated from number 12 in clock. Angle formed by a circular clock 360 0 Angle of minute and hour hand calculated from Number 12 Time taken by minute  hand for  one revolution 360 0 =60min                             Angle formed by minute hand in I min 1min =6 0 Time taken by hour hand in one revolution 360 0 = 12 hours Angle formed by hour hand in 1 hour 30 0 = 1 hour                           Angle between hour and minute hand at 2 45 Convert 2Hr45Min into hours =2+(45/60) =2+(3/4) =(8

 In many competitive exams there are questions from clock problems in this blog it is clearly explained the different types problems.  Analog clock is considered as circle.
