Reasoning Tasks

Complex Reasoning Example:

Problem: A company has 3 departments. Dept A has 50 employees, 
Dept B has 30% more than A, and Dept C has half the combined 
total of A and B. What's the total employee count?

Kimi K2.5 Solution:
1. Dept A = 50
2. Dept B = 50 × 1.30 = 65
3. Combined A+B = 115
4. Dept C = 115 / 2 = 57.5 → 58
5. Total = 50 + 65 + 58 = 173 employees

GLM 4.7 Solution:
Similar correct solution with comparable reasoning chain.
