Two lines are drawn at right angles one being a tangent to `y^(2) = 12x` and the other to `x^(2) = 111116y`. If the locus of their point of intersection is `(x^(2)+y^(2))(lx+my)+(nx-3y)^(2)=0` then `l+n-m` is equal to |

Answer» Correct Answer - C Tangets on both the parabolas `y = mx +(3)/(m),y = mx-4m^(2)` `m^(2)x- my +3=0,4m^(2)-mx+y=0` eliminating m we get the locus |
