A) \[\frac{17}{16}\]
B) \[\frac{17}{8}\]
C) \[\frac{17}{4}\]
D) \[\frac{15}{4}\]
Correct Answer: B
Solution :
Given, 3 x+y = 81 or, 3x+y = 34 or, x+ y= 4 ..(i) and 81x-y = 3 or, (34) x-y =32 or, x ? y = \[\frac{1}{4}\] ...(ii) On solving the equation (i) and (ii), we get - 2x =\[\frac{17}{4}\] ; x = \[\frac{\mathbf{17}}{\mathbf{8}}\]You need to login to perform this action.
