Data Sufficiency — Sales computation: How many New Year's greeting cards were sold this year in your shop? Statement I: Last year 2,935 cards were sold. Statement II: This year's sales were 1.2 times last year's sales. Decide which statement(s) are sufficient to compute this year's total. Choose the correct sufficiency option.

Difficulty: Easy

Correct Answer: Both statements I and II together are sufficient, but neither alone is sufficient.

Explanation:


Why not I alone?
I gives only last year’s number (2,935), not this year’s ratio ⇒ insufficient.


Why not II alone?
II gives a multiplier (1.2×) but no base number ⇒ insufficient.


Combine I + II
This year = 1.2 × 2,935 = (12/10) × 2,935 = 3522 cards.
Final Answer
Both statements together are sufficient (and they yield 3,522).
