What is the OA? I also get .f2001290 wrote:In the decimal representation of x, where 0 < x < 1, is the tenths digit of x nonzero?
(1) 16x is an integer.
(2) 8x is an integer.
I went with B, but the OA doesn't go with me:)
Statement 1:
For 16x to be an integer, such that 0 < x < 1,
16x < 16,
16x = 15, in which case tenth's digit of x is NOT 0.
OR, 16x = 1, in which case tenth's digit of x is 0.
NS.
Statement 1:
For 8x to be an integer, such that 0 < x < 1,
8x < 8.
Say, 8x = 7, in which case tenth's digit of x is NOT 0.
OR, 8x = 1, in which case tenth's digit of x is NOT 0.
Sufficient.
