Answered by Steve
LCM(25,30) = 150 minutes

11:00 + 2:30 = 13:30, or 1:30 pm

. It takes Riaz 30 minutes to mark a paper, Razi only takes 25 minutes to mark a paper, if they both start marking a paper at 11:00 AM, what is the first time they will finish marking a paper at same time?
Answered by Arooj Saif
LCM of 25,30 = 5x5x3x2 = 150 minutes
10:00Am to 11:00AM = 60 Minutes
11:00Am to 12:00Pm = 60 Minutes
12:00pm to 12:30 pm= 30 minutes
60min+ 60min+30min = 150 Minutes
So the time is 12:30AM
