Answer

4 teachers were from G-Secondary School.

Solution

Step 1: Calculate the number of NCD teachers. • 40 teachers attended the workshop. • 60% of the teachers came from other provinces, so 40 × 0.60 = 24 teachers came from other provinces. • Therefore, the remaining teachers from the National Capital District (NCD) = 40 − 24 = 16 teachers. Step 2: Determine the number of G‑Secondary School teachers among the NCD teachers. • Given that 25% of the NCD teachers were from G‑Secondary School, calculate 25% of 16:   16 × 0.25 = 4 teachers. Answer: 4 teachers were from G‑Secondary School.

Bonus Knowledge

Out of the 40 teachers attending the workshop, \( 60\% \) from other provinces means there were \( 0.6 \times 40 = 24 \) teachers from outside the National Capital District (NCD). This leaves \( 40 - 24 = 16 \) teachers from NCD. If \( 25\% \) of these NCD teachers are from G. Secondary School, then \( 0.25 \times 16 = 4 \) teachers are from G. Secondary School. So, there are 4 teachers from G. Secondary School!
