Question

Four clocks rings at the interval of 6sec,8sec,12sec and 18 second respectively . if they ring together at 12am then how many times will they ring together within the time span of 6minutea

Answer 1

Answer: The answer is 5 times.

Step-by-step explanation: We are given four clocks which rings at intervals of 6 sec, 8 sec, 12 sec and 18 sec.

So, they ring together at an interval of  lcm(6, 8, 12, 18) = 72 seconds.

They ring together at 12 am. In a time span of 6 minutes, i.e., 6×60 seconds i.e., 360 seconds, the number of times the four clocks ring together is given by

$\dfrac{360}{72}=5.$

Thus, the number of times is 5.

Answer 2

Answer:

Answer: The answer is 5 times.

Step-by-step explanation: We are given four clocks which rings at intervals of 6 sec, 8 sec, 12 sec and 18 sec.

So, they ring together at an interval of lcm(6, 8, 12, 18) = 72 seconds.

They ring together at 12 am. In a time span of 6 minutes, i.e., 6×60 seconds i.e., 360 seconds, the number of times the four clocks ring together is given by

\dfrac{360}{72}=5.

72

360

=5.

Thus, the number of times is 5.
