Explanation & Answer

Piano lesson every seventh day and cooking classes every fourth day.

Find the LCM to find the days in which they coincide.

LCM of 4 and 7 = 28


It is mentioned that today you have both lessons. So today is the 28th day and every 28th day both the classes will coincide.


So in 28 days you will have both lessons on same day.
