Fruit

There are a total of 28 pear and apple trees in the orchard, and no other fruit trees. The numbers of pear trees and apple trees are in the ratio 3:4.
Which statement is false?
A. Apple trees make up 4/7 of the fruit trees.
B. There are fewer pear trees than apple trees.
C. There are 1/4 fewer pear trees than apple trees in the orchard.
D. There are 4 more apple trees than pear trees.

Final Answer:

x = A

Step-by-step explanation:

$$\begin{gathered} a=28 \\ h:j=3:4 \\ h=\frac{3}{3+4}\cdot a=\frac{3}{3+4}\cdot 28=12 \\ j=\frac{4}{3+4}\cdot a=\frac{4}{3+4}\cdot 28=16 \\ A \\ {j}_2=\frac{3}{4}\cdot a=\frac{3}{4}\cdot 28=\frac{3\cdot 28}{4}=\frac{84}{4}=21 \\ B \\ j>h \\ C \\ {h}_2=j-j/4=16-16/4=12 \\ D \\ {j}_3=h+4=12+4=16 \\ x=A \end{gathered}$$
