I think the answer should be A.

x is the hours worked by John.
y is the hours worked by Larry.
x+y=7

Statement I

3x+4y=25

We can solve the two equation to get the values for x and y.

Sufficient.

Statement II

Larry assembled more chairs as compared to John.

We dont know how much time did each guy worked for.

Insufficient.


Hence A.

Whats the OA?
