Logical Reasoning(Master ) Clock

A clock strikes 4 taking 9 seconds. In order to strike 12 at the same rate, the time taken is

27 seconds

36 seconds

30 seconds

33 seconds

There are 3 intervals when the clock strikes 4
Time taken at 3 intervals = 9 seconds

Time taken for 1 interval = 93 = 3 secondsTime taken for 1 interval = 93 = 3 seconds

In order to strike 12, there are 11 intervals, hence, time needed

= 3 × 11 = 33 seconds

Hence, option 4 is the correct answer.
