## close to 10^(-2)

Is number A more close to 10^(-2) or 10^(-3)?

(1) A is more close to 10^(-1) than to 10(-4)
(2) A is more close to 10^(-2) than to 10(-4)
Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient.
Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient.
BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
Each statement ALONE is sufficient to answer the question.
Statements 1 and 2 TOGETHER are NOT sufficient to answer the question.

Whats the best way to solve this?

Let's see...

Is A closer to 0.01 or 0.001

For this to be true, A must be > (0.01+0.001)/2 ie A>0.0055 or A>0.01

1) A is closer to 0.1 than it is to 0.0001

=> A > 0.05005 or A > 0.1

2) A is closer to 0.01 than it is to 0.0001

=> A > 0.00505 or A> 0.01

From 1) we can say that A>0.0055 or A>0.01 Suff

From 2) we cannot say for sure

Hence A
