The neighbors Elza, Sueli, Patrícia, Heloísa, and Cláudia arrive together from work and start climbing the stairs of the five-story building where they live. Each one lives on a different floor. Heloísa arrives at her floor after Elza, but before Cláudia. When Sueli reaches her floor, Heloísa still has two floors to climb, and the same happens with Patrícia when Elza arrives at her floor. Sueli does not live on the first floor. On which floor does each one of them live?
"Heloísa arrives at her floor after Elza but before Cláudia" means that Heloísa lives above Elza and below Cláudia, and "When Sueli arrives at her floor, Heloísa still has 2 floors to climb, and the same occurs to Patrícia when Elza arrives at her floor" means that Heloísa lives two floors above Sueli and Patrícia two floors above Elza. However, since Sueli does not live on the first floor and Heloísa lives two floors above Sueli, either Sueli lives on the second and Heloísa on the fourth or Sueli lives on the third and Heloísa on the fifth. But Cláudia lives above Heloísa, so Heloísa cannot live on the top floor, the fifth. Thus, Sueli lives on the second floor, Heloísa on the fourth, and Cláudia on the fifth. Finally, Patrícia lives two floors above Elza, so Elza lives on the first floor and Patrícia on the third floor.
