Solution: Determine a) the value of antique as on Jan 1 and Dec 31
or b) ratio of value as on Jan 1 and Dec 31
Statement 1: The value of the antique on January 1, 1981, was $3,000
We only know the value as on Jan 1, but not as on Dec 31 - Insufficient

We know the ratio of value as on Jan 1 and Dec 31 (100% rise) - Sufficient

Note we need to calculate %increase and not value of the object.
S(1): Gives value at the beginning. No way to calculate value at the end. Hence Not Sufficient.
S(2): Tell us that the value doubled. Hence we know the % increase i.e 100%. Hence Suff.
Answer B.
