A) 24 s
B) 12 s
C) \[8\frac{8}{11}\,s\]
D) \[8\frac{2}{11}\,s\]
Correct Answer: C
Solution :
There are 11 intervals when the clock strikes 12. Time taken for 11 intervals = 48 s. \[\therefore \] Time taken for 1 interval \[=\left( \frac{48}{11} \right)s\] In order to strike 3, there are 2 intervals, for which the time taken \[=\left( \frac{48}{11}\times 2 \right)s=8\frac{8}{11}s.\]You need to login to perform this action.
