A person standing at the junction (crossing) of 2 straight paths represented by the equations 2x − 3y + 4 = 0 and 3x + 4 y − 5 = 0, wants to reach the path whose equation is 6 x − 7 y + 8 = 0 in the least time, then the equation of the path he should follow is

  1. A 119x − 102 y − 125 = 0
  2. B 119x + 102 y − 125 = 0
  3. C 102 x + 119y − 125 = 0
  4. D 102 x − 119y + 125 = 0
Verified Solution

Answer & Solution

Correct Answer

(B) 119x + 102 y − 125 = 0

Step-by-step Solution

Detailed explanation

Given, a person is standing at the junction of the lines, 2x − 3y + 4 = 0 … (i) 3x + 4y − 5 = 0 … (ii) Solution of Eqs. (i) and (ii) will be the junction point, where the man is standing. On solving Eqs. (i) and (ii), \(x=\frac{-1}{17}\) and \(y=\frac{22}{17}\) \(\therefore\)…
