What is the value of the tenths digit of number x?
(1) The hundredths digit of x is 5
(2) Number x, rounded to the nearest tenth, is 54.5
X = .ABC....
1 - X=.A5C... Obviously insuff
2. INSUFF. we dont know if it was 54.45 or 54.52 so hard to tell
combine them? Well we know X = .A5 and that if we were to round up the digit A will go up by 1 so SUFFICIENT
