Clock Puzzle
Sitting uncomfortably in the doctor’s waiting room one day, I stared at the clock on the wall. I had been waiting for what seemed to be a very long time.
To take my mind off the reason for the visit I started to invent little puzzles to solve.
Estimating the length of the minute hand of the clock to be 4 inches, I calculated the distance the hand had travelled around the clock since I arrived to be 15 inches.
How long had I been waiting?

Eligibility criteria for CAT
The candidate must hold a Bachelor’s Degree, with at least 50% marks or equivalent CGPA [45% in case of the candidates belonging to Scheduled Caste (SC), Scheduled Tribe (ST) and Differently Abled (DA)categories], awarded by any of the Universities incorporated by an act of the central or state legislature in India or other educational institutions established by an act of Parliament or declared to be deemed as a University under Section 3 of the UGC Act, 1956, or possess an equivalent qualification recognized by the Ministry of HRD, Government of India.
The percentage of marks obtained by the candidate in the bachelor’s degree would be calculated based on the practice followed by the university/institution from where the candidate has obtained the degree. In case the candidates are awarded grades/CGPA instead of marks, the conversion of grades/CGPA to percentage of marks would be based on the procedure certified by the university/ institution from where they have obtained the bachelor’s degree. In case the university/ institution does not have any scheme for converting CGPA into equivalent marks, the equivalence would be established by dividing the candidate’s CGPA by the maximum possible CGPA and multiplying the result with 100.

How to Find the Average Speed?
Lot of students gets confused while finding out the average speed, when various distances are travelled with different speed. Say for example, trip to Agra from Delhi is made at an average speed of 40 km/hr and the trip back at an average speed of 60 km/hr. Find their average speed for the entire trip. (Hint: It's Not 50 Km/hr)
Rule: If a person travels a distance at a speed of x km/hr and the same distance at a speed of y km/hr, then the average speed during the whole journey is given by 2xy/x + y km/hr.
Or, If a person travels half the distance at a speed of x km/hr and the other half at a speed of y km/hr, then the average speed during the whole journey is given by 2xy/x + y km/hr.
So answer to the above question:
(2*60*40)/(60+40) Â = 48 Km/hr
If a person travels three equal distances at a speed of x km/hr, y km/hr and z km/hr respectively, then the average speed during the whole journey is 3xyz/xy + yz + xz km/hr.
This problem can also be dealt with assuming some hypothetical distance.
