3. Two sisters, Marija and Ljiljana, sold apples from their orchard. They sold a kilogram of apples for 7 kuna. Marija earned $434 \mathrm{kn}$ from the apples sold, and Ljiljana earned $875 \mathrm{kn}$. What was the yield of apples from their orchard if Marija was unable to sell $102 \mathrm{~kg}$, and Ljiljana $76 \mathrm{~kg}$ of apples?
First method:

Maria earned $434 \mathrm{kn}$ from selling apples, which means she sold $434: 7=62 \mathrm{~kg}$. $\quad 2$ POINTS

Before the start of the sale, Maria had $62+102=164 \mathrm{~kg}$ of apples. 2 POINTS

Ljiljana earned $875 \mathrm{kn}$ from selling apples, which means she sold $875: 7=125 \mathrm{~kg}$. $\quad 2$ POINTS

Before the start of the sale, Ljiljana had $125+76=201 \mathrm{~kg}$ of apples. 2 POINTS

The apple harvest from their orchard was $164 \mathrm{~kg}+201 \mathrm{~kg}=365 \mathrm{~kg}$. 2 POINTS

TOTAL 10 POINTS
