Two alarms toll at intervals of 24min
tou
and 36 min. respectively. If they
together at 9 am after how many
minutes do they too together again
at the earliest ?​

Answer 1

They toll toether again after 12 minutes....

36 = 24 * 1 + 12

24 = 12 * 2 + 0

Therefore , the HCF is 12 and hence they toll at 12 minutes together...
