The hands of a clock meet at an interval of 10 mins, 15mins and 25 mins. If they last met at 11 am, at what time will they again meet?​

Answer»

er : take out the least common multiple of 10,15 ,25 so the LCM is 150

so 150 min = 2 hours and 30 minutes

so 11am+ 2hours and 30 minutes is 1:30 PM

hope U understood
