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.

My doubt: what is tenths digit?

0.XYZ

X is the 10ths digit of the decimal representation
Y is the 100ths digit
Z is the 1000th digit

Example: 1.23---2 is the 10ths digit of the decimal representation.

Tenths digit is the number that comes immediately after the decimal.

.27 will have tenths digit of 2

.30 -> tenths digit 3

2 different answers possible

Always when a specific value is asked in a DS question the statements individually or together must lead us in to one definite answer

Hence E)

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
