Whether the two statements give ENOUGH information to answer the question — not what the final numerical answer is. You judge sufficiency, you do not compute the answer.

DS only requires deciding whether a unique answer CAN be determined. Fully solving wastes time and tempts you to pick a choice based on the value rather than on sufficiency.

Two statements, labeled (1) and (2). You evaluate each for sufficiency, alone and together.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
