    Direction: In each question, two equations numbered I and II are given. You have to solve both the equations and mark the appropriate option. Give answer
    I. \[9x+8y=64\]                       II. \[3x+4y=28\]

    A)  if x > y                       

    B)  if x < y           

    C)  if x < y          

    D)  if x > y           

    E)    if x = y or relationship between x and y can't be established.

    Correct Answer: C

    Solution :

    \[9x+8y=64\]    ?(i) \[3x+4y=28\]    ... (ii) Solving equation (i) - (ii)\[\times \]3, we get 8y\[-\]12y = 64\[-\]84 \[\therefore \]  y = 5 Putting the value of y in equation (i), we get \[9x=64-40\] or, \[x=\frac{24}{9}=\frac{8}{3}\] Hence x < y
