18 mango trees and 5 apple trees are planted on the left side of the entrance. Whereas, a total of 30 trees are planted on the right side, but 9 of them wilt and are removed.
Select the correct equation that represents the trees on both sides of the entrance.

The correct option is B $18+5\ne 30-9$
Let us calculate the total number of trees on both sides of the entrance.

Left hand side		Right hand side
18+5	$\ne$	30-9
23	$\ne$	21

So, we can say that both sides do not have an equal number of trees.

Therefore, we can conclude that $18+5\ne 30-9$ is the equation that represents the trees on both sides of the entrance.

Hence, Option B is correct.
