Answer 1

LCM of 3 and 4 is 12.

Since they have met on 1st of this month, they will meet again on (1+12)=13th of this month.

Prasad and raju met on the 1st.

The next they can meet only on a day which can be divided by both 3 and 4, because Prasad goes to market every 3rd day and Raju goes every 4th day.

This means that we have to find the lowest common multiple of these two numbers.

The LCM of 3 and 4 is 12. 

So the next day when they meet will be 12 days after their first meeting. 

i.e. on the 13th of the month.
