Glad nie Redelik goed Goed Uitstekend Ek kon die bedrag van ons gesin se akkommodasie korrek bereken. Glad nie Redelik goed Goed Uitstekend

#### KOPKRAPPER!

Vusi is ’n passasier op ’n veerboot. Hy let op dat by die eerste halte 18 mense opklim en 13 afklim. By die volgende halte klim 41 mense op en 29 klim af. By die derde halte het 53 mense opgeklim en 27 het afgeklim. As daar toe 233 mense op die veerboot oor was, hoeveel mense was klaar op die veerboot toe Vusi opgeklim het?
