Neco 2024 Christian Religious Studies Question 20

In Acts 13:1‑3, the church at Antioch sent out Paul and Barnabas on their first missionary journey. Later, in Acts 14:21‑23, they returned to Antioch and reported that they had appointed elders in each church they had founded. Suppose the church at Antioch originally had 120 members. During the journey, they planted 3 new churches, each receiving 15 new believers from the original group, and each new church later appointed 4 elders. After the journey, the original Antioch church lost 30 members who joined the new churches, but 20 new believers joined Antioch from elsewhere. The Antioch church also appointed 5 elders as part of strengthening its leadership. How many elders in total were appointed across all churches (including Antioch) after the journey? Provide the total number.
