Chukwuma was engaged as an agent by Segun to negotiate the purchase of a commercial building. Chukwuma secretly purchased the building himself through a front company for ₦80,000,000 and resold it to Segun for ₦100,000,000, falsely representing that the vendor refused to accept anything less. Segun paid the ₦100,000,000 purchase price and also paid Chukwuma his agreed 5% agency commission of ₦5,000,000. Upon discovering the fraud, what is the total monetary amount Segun is entitled to recover from Chukwuma under the Law of Agency?
