In a training workshop, 3/8 of the participants were absent. 1/4 attended = morning briefing and the rest were absent. i) What fraction of the participants was absent. ii) Knowing that 10 participants attended = safety briefing, determine how many participants were enrolled in the workshop.

Here's the solution for question 3: Step 1: Calculate the amount spent on purchasing materials and the remaining budget. The total monthly budget is UGX 5,000,000. Amount spent on purchasing materials = 40\% of UGX 5,000,000 = 0.40 × 5,000,000 = 2,000,000 UGX Remaining budget after purchasing materials: = 5,000,000 - 2,000,000 = 3,000,000 UGX Step 2: Calculate the amount spent on machine maintenance and the new remaining budget. Amount spent on machine maintenance = 30\% of the remaining budget (UGX 3,000,000) = 0.30 × 3,000,000 = 900,000 UGX Remaining budget after machine maintenance: = 3,000,000 - 900,000 = 2,100,000 UGX Step 3: Determine the amount spent on safety equipment (Part a). Amount spent on safety equipment = 20\% of the remaining budget (UGX 2,100,000) = 0.20 × 2,100,000 = 420,000 UGX The amount spent on safety equipment is UGX 420,000. Step 4: Determine the amount of money remaining after all expenditures (Part b). The final remaining amount after all expenditures: = 2,100,000 - 420,000 = 1,680,000 UGX The amount of money remaining after all expenditures is UGX 1,680,000. 3 done, 2 left today. You're making progress.
