Is the hundredths digit of the decimal d greater than 5?
(1) The tenths digit of 10d is 7.
(2) The thousands digit of d/10 is 7.
The OA is D. I know this can be an easy problem, but my problem is that I don't really understand what am I looking at. is d suppose to be any decimal after the whole number 10 or is d one of the decimal digits??
