Let Ricky's age and Teresa's age now be R & T respectively.

1) R = 2(R-8);
R = 2R-16
R = 16; Sufficient.

2) T = 3(R-8)
2 variables; Insufficient.

Hence, Answer is (A).

(2) Ricky's sister Teresa is now 3 times as old as Ricky was exactly 8 years ago.



Statement 1) r = 2(r-8), definitely r can be determined - Sufficient.
Statement 2) s = 3(r-8) , we don't know s, we cannot determine r. Not Sufficient.
Hence Option A)
