Let a,b c and d be non-zero numbers. If the point of intersection of the line 4ax+2ay+c=0 and 5bx+2by+d=0 lies in the fourth quadrant and is equidistant from the two axes then: a. 3bc-2ad=0 b. 3bc+2ad=0 c. 2bc-3ad=0 d. 2bc+3ad=0

A

2bc-3ad = 0

B

2bc+3ad=0

C

3bc-2ad=0

D

3bc+2ad=0

Text Solution

Verified by Experts

Since point of intersection lies in IV quandant and equidistant from axes, but the point of intersection be `(h, -h), h gt 0`
`rArr 4ah-2ah+c=0`
and 5bh -2bh+d = 0
`"So, "-(c)/(2a) = -(d)/(3b)`
`rArr 3bc-2ad = 0`
