A clock takes 9 seconds to strike 4 times. In order to strike 12 times at the same rate, the time taken is:
-
- 27 seconds
- 36 seconds
- 30 seconds
- 33 seconds
Correct Option: D
As we can say that ,
There are 3 intervals when the clock strikes 4 Time taken in 3 intervals = 9 seconds
∴ Time taken for 1 interval = 3 seconds
In order to strike 12, there are 11 intervals, for which the time taken is 11 × 3 seconds = 33 seconds.
Therefore , Required time taken is 33 seconds .
