 Jerry ana riwaya ya kuvutia aliyokopa kutoka kwa rafiki yake ili aisome mwishoni mwa wiki. Kitabu hicho kina kurasa 93. Jumamosi, anasoma kurasa 30. Jumapili, anaenda kanisani na anarudi, anakaa chini na kusoma kurasa 20 za kitabu. Kurasa ngapi zimesalia kabla Jerry hajamaliza kitabu?


### Response:
 Jerry anaposoma kurasa 30 Jumamosi, atakuwa amesalia na kurasa 93 - 30 = <<63=63>>63.
Baada ya kusoma kurasa 20 zaidi Jumapili, atakuwa amesalia na kurasa 63 - 20 = <<63-20=43>>43.
