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 |
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 < yYou need to login to perform this action.
