$10,000 is deposited in a certain account that pays r percent annual interest compounded annually, the amount D(t), in dollars, that the deposit will grow to in t years is given by D(t) = 10,000 {1+(r/100)}t. What amount will the deposit grow to in 3 years?
(1) D(t) = 11,000
(2) r =10
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.

My answer is different from the OA given in SET.Please let me know your views

formulae : D(t) = 10,000 {1+(r/100)}t


stmt 1:
D(t) = 11,000 now here t& r are not known and I dont think we can assume t=3, well in that case it should have been D(3) =11000
Not Suff

stmt 2: r=10, t=3 put these in formula we would get the amt.

suff

so my ans is B
