Question: The diagonal passing through origin of a quadrilateral formed by $ x=0,\ y=0,\ x+y=1 $ and $ 6x+y=3, $ is [IIT 1973]

Options:

A) $ 3x-2y=0 $

B) $ 2x-3y=0 $

C) $ 3x+2y=0 $

D)None of these

Answer:

Correct Answer: A

Solution:

  • diagonal BD is passing through origin, therefore its equation is given by $ ( y-\frac{3}{5} )=\frac{-(3/5)}{-(2/5)}( x-\frac{2}{5} ) $
    Þ $ 3x-2y=0 $ .
