[BTGmoderatorDC]

A certain wooded lot contains 56 oak trees. How many pine trees does the lot contain?

(1) The ratio of the number of oak trees to the number of pine trees in the lot is 8 to 5.

(2) If the number of oak trees were increased by 4 and the number of pine trees remained unchanged, the ratio of the number of oak trees to the number of pine trees in the lot would be 12 to 7.

Statement 1: Oak : Pine = 8:5
i.e. Oak = 56 then Pine = 35
SUFFICIENT

Statement 2: (Oak+4):Pine = 12:7
i.e. (56+4):Pine = 12:7
i.e. Pine = 35
SUFFICIENT

Therefore, __D__ is the correct answer.
