Ques:- In a Park, N persons stand on the circumference of a circle at distinct points. Each possible pair of persons, not standing next to each other, sings a two-minute song ? one pair immediately after the other. If the total time taken for singing is 28 minutes, what is N?
Recent Answer : Added by Admin On 2022-09-29 18:42:28:
Total number of pairs is NC2^{N}C_2NC2. Number of pairs standing next to each other = N. Therefore, number of pairs in question = NC2^{N}C_2NC2 – N = 28/2 = 14. If N = 7,
7C2 – 7 = 21 – 7 = 14….
N =7

Ques:- A train running at the speed of 60 km/hr crosses a pole in 9 seconds. Find the length of the train?
Recent Answer : Added by Admin On 2022-09-29 15:10:14:
Time =9 seconds
Speed =(60×518) m/sec=(503)m/sec
∴ Speed =DistanceTime
Length of the train (Distance) = (Speed × Time) = (503×9) m=150 m.

Ratio of diameters=1:2
Ratio of radius=1:2
