Ans E
In both cases, we dont know how many trees in 1 row.
If we take the 2 together we still dont know how many maximum no of trees can be there in 1 row. The question doesnt say trees are equally divided.

1) Total number of trees are 225.

NS ..no infromation about tree per row
2) There are 12 rows of trees.
no infromation about tree per row ....NS

taken together ....still NS cause each row can have any no of tree starting from 1 to 213

(1) Can be any variation... E.g. (Row,Column) = (15,15) or (5,45) or (45,5) etc. The row will give us number of rows, while the column will give us number of trees in each row. Not sufficient as there's many possibilites.

(2) We're told there are 12 rows of trees. But we do not know how many trees are in the orchard. So not sufficient.

(1) and (2)... could have rows 1-11 having 19 trees and row 12 having 16 trees, or 1-11 having 10 trees and row 12 having 115 trees... etc... so not sufficient as there's many possibilites.
