A) \[\frac{211}{19}s\]
B) \[\frac{1217}{19}s\]
C) \[\frac{1218}{19}s\]
D) \[\frac{1018}{19}s\]
Correct Answer: C
Solution :
[c] Time gap between two consecutive ticks \[\frac{58}{57}\,\,\sec .\] and \[\frac{609}{608}\,\,\sec .\] \[\therefore \] Required time = LCM of \[\frac{58}{57}\] and \[\frac{609}{608}\] \[=\frac{LCM\,\,o\text{f}\,\,\text{58}\,\,\text{and}\,\,\text{609}}{HCF\,\,o\text{f}\,57\,\,\text{and}\,\,608}=\frac{1218}{19}\sec \]
