Pdf Summary

The homework presented is a logical reasoning exercise for Math Kangaroo Class Level 3-4, comprising five distinct problems.<br /><br />1. **Problem 1**: Involves arranging nine children in a circle while ensuring that no two boys stand together and no three girls are together. The task is to identify the correct possible number of boys in this arrangement.
