As I am going through the OG12
and other sources, I notice the use of when to consider a negitive (or similar) inconsistent during answer explainations from the question makers.
For example, today I came across this DS question:OG12
question 43 page 276
What is the tenths digit in the decimal representation of a certain number?
1) the number is less than 1/3
2) the number is greater than 1/4
The OA states:
1) Since the number is less than 1/3, the tenths digit can be 0,1,2, or 3; NOT sufficient
2) Since the numebr is greater than 1/4, the tenths digit can be 2,3,4, ..., 9; NOT sufficient
My contention is that the OA doesn't take into consideration negitive numbers for S1, nor numbers greater than 1 for S2. Because of this, the tens digit could be any number 0-9 for either S1 or S2. Of course, in this question it doesn't affect the outcome of the correct answer being E; but I have seen questions inconsistently consider negitives or not
Any insight as to when to ignore negitives (or other bounds like non-integer/fractions) despite the question not stating it in any manner?
