it takes pandulum of a clock 7 second to strike 4'o clock.How much time(in seconds) will take to strike 11'o clock
a)23.33
b)20
c)18
d)none of them.

• The more relevant thing in this case is not the number of strikes but the number of time intervals.
  
  If a clock has to strike 4, there are 3 time intervals between the 4 strikes So, in 7 seconds the pendulum elapses 3 time intervals.
  
  To strike 11, there has to be 10 time intervals, which will take (10 x 7)/3 = 23.33 seconds.
