Bunuel
\(\frac{UNIT}{TENS} = \frac{1}{2}\)
so the digits can be \(\frac{4}{8}\) or \(\frac{3}{6}\) or \(\frac{2}{4}\) or \(\frac{1}{2}\) (QUESTION STEM)
Number can be 84,63,42,21
(1) The sum of the digits multiplied by the tens digit is 54
(6+3) x 6=54=> number is 63
(2) The product of the digits divided by 2 is 9
\(\frac{(6 x 3)}{2}=9\)
THE ANSWER IS D

Answer is D
Possible out comes of X could be : 42,63,84 since here the ratio between unit and tenth digit is 1/2
data 1 says that the sum of unit and ten digit TIMES to ten digit is 54 . Here , the only option which yields 54 under this condition is 63 since (6+3) *6 =54
so here the answer is clearly 63 and this data is sufficient.
data 2 says that unit*ten/2 =18 So here 6*3/2 = 9 and only answer here is 63 too and this data is sufficient too
1 & 2 are both sufficient and answer is D
