very well done Vaish........

its d) 4.........just see how..........

Hey buddy,,,,,,,,

well.....simple application.......

for any homogeneous equation of pair of lines passing through origin........

joint equation of the pair of angle bisectors is given by........

here we have.........

a = 1, b = -1, h = -m      {considering first equation}

then joint equation of the pair of angle bisectors comes out to be,,,,,,,

Now compare it with the second equation.......and u will get the answer,,,,,,

The first Number between 1 to 1000........which when divided by 7 gives 1 remainder is 8......and the last one is 995.......so total such numbers are.....142.......using Arithematic Progression.......

and thus req.Probability  = 142 / 1000 = 71 / 500........
