If a certain machine produces bolts at a constant rate, how many seconds will it take the machine to produce 300 bolts?
(1) It takes the machine 56 seconds to produce 40 bolts.
(2) It takes the machine 1.4 seconds to produce 1 bolt.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.


IMO A
This time no looking back!!!
