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. \[6x-5y=70\] II. \[2x-7y=-30\] |
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: A
Solution :
I.\[6x-5y=70...\text{ }(i)\] II. \[2x-7y=-30\] Solving (i) ? (ii) \[\times 3\], we get \[16y=160\] \[\therefore y=10\] Now, putting the value of y in equation (i), we get \[x=20\] Hence \[x>y\]You need to login to perform this action.
