See this once
Its confusing , by graphing 28 I'm getting prism
But If I apply cramers rule I get a common point
For 29 I'm getting A
Shouldnt ∆ be 0 for it to be a prism
Delta will be zero for prism along with the added condition that deltax deltay and deltaz neither of them is 0
So acc to me 28 D
Hmm..me too getting 28 d and 29 a.
Then given answer must be wrong..
Thanks for confirming @Mayank_Chowdhary @Chirag_Hegde
You know that the line will be of the form (x-1)/l = (y-1)/m = (z-1)/n since the line passes through 1,1,1
Now just male the distance between the lines zero You will get the ratio of l:m:n
for Exam just substitute the point
Got it ! Thanks @Mayank_Chowdhary bro
Bro can you do 25 on paper please?
And this one too
Is it (a) @Chirag_Hegde ?
D is given but post the solution o think wrong answer is given
Same way as @Mayank_Chowdhary said in earlier post.
Question 25 also can be done in a
similar way @Chirag_Hegde
Do you want working @Chirag_Hegde or cleared?
Thank you I got it
