Question

Four bells toll at intervals of 3,7,12 and 14 minutes. The four bells toll together at 12 O'Clock. When will they again toll together?

Answer 1

Answer:

1:24

Step-by-step explanation:

= LCM of 3,7,12,14 = 84 = 1 h 24 m = 12:00+1:24 = 13:24 = 13:24-12:00 = 1:24

Answer 2

Answer:

L.C.M of 3,7,12,14 = 84

so, Four bells toll at intervals of after 84 minutes.

84 minutes = 1hr 24 min

so, The bell tall again after 12 O'clock is 12:00 + 1 hr 24min

=) 1 :24 P.M
