La un atelier de croitorie, dintr-un balot de stofa de 540,85m se confectioneaza 150 de pant. si 80 de costm. Cata stofa ram. dc. pt. un pant. se foloseste 1[tex] \frac{1}{5} [/tex] m, iar pt. un cost. 2[tex] \frac{3}{10} [/tex] m ?

Răspuns :

pantalon=6/5m=12/10m  costum=23/10m  => 151x6/5+80x23/10=181,2m+184m=365,2m =>
raman 540,85m-365,2=175,65 m ramase
