NFER 11A Q50: a milkman and a baker
Hi. I need help with this particular exercice.
A milkman and a baker deliver to the same house.
In a period of 28 days, the milkman calls every second day and the baker every third day.
They meet at the house twice in the first 7 days.
How many more times do they meet during the 4 week period?
Please...

Re: NFER 11A Q50: a milkman and a baker
The milkman and baker meet every 6 days (the smallest common multiple of 2 and 3). To see this, it might help to start with a number line, and draw one colour hopping every second day and another hopping every third day. We're told they met twice in the first 7 days, so they must have met on the 1st and 7th days. They will meet again on the 13th, 19th and 25th days, i.e. 3 more times.london_ilusion wrote:A milkman and a baker deliver to the same house.
