 Paka mdogo yatima alikuwa na urefu wa inchi 4 alipatikana. Katika wiki mbili zijazo, aliongezeka mara mbili urefu wake, na alipofikisha miezi 4, aliongezeka mara mbili tena urefu wake. Urefu wake wa sasa ni upi?

 Baada ya wiki mbili, paka huyo alikuwa na urefu wa inchi 4 x 2 = <<4*2=8>>8.
Baada ya miezi 4, paka huyo alikuwa na urefu wa inchi 8 x 2 = <<8*2=16>>16.
