100% - 45% = 55%
a) 110 : 55% = 200 tone cantitatea exportata
b) luna 1⇒ 200 × 45% = (200×45):100 = 90 tone
a) 110 : 55% = 200 tone cantitatea exportata
b) luna 1⇒ 200 × 45% = (200×45):100 = 90 tone
1) 45x / 100 = 9x=20
2) 110 t
9x/20+110 =x numitot 20
9x+2200 =20x
20x-9x =2200
11x=2200
x = 200 t
1)9x/20 =9*200/20 =90 t
2) 110 t
9x/20+110 =x numitot 20
