Solve the following problem using Gauss Jordan Maria got a loan in a total of 12,400Php last week from the rental of three BNB properties. She had to pay 10% of the rent from the duplex for repairs, 20% of the rent from the townhouse for repairs, and 30% of the rent from the apartment for repairs. If the apartment rents for twice as much as the duplex and her total repair bill was 2,760, then what is the rent for each property?
