## Question

### Solution

Correct option is

None of these

The point of intersection of

x + 2y – 3 = 0 and 2x + 3y – 4 = 0

is found to be (–1, 2), The coordinates of this point satisfy the equation 4x + 5y – 6 = 0 but not 3x + 4y – 7 = 0. Hence all the four lines are not concurrent. Again since three of the lines meet at a point they cannot from a quadrilateral.
