**Solution:**

If you come across questions that apart **from directly mentioning "remainders" hint at grouping ****/mention intervals/divisions in classes, **you may direct your thinking towards the concept of remainders in such cases.

For ex:-Royal Club has more than 10 but fewer than 40 members. Sometimes the members sit at tables with 3 members at one table and 4 members at each of the other tables, and sometimes they sit at tables with 3 members at one table and 5 members at each of the other tables. If they sit at tables with 6 members at each table except one and fewer than 6 members at that one table, how many members will be at the table that has fewer than 6 members?
