Hi Bunuel,

if we substitute p=0 then the answer must be 6. There can be no other answer right?


Not sure I understand what you mean...

p = 0, as well as any other value of p less than or equal 6 satisfies |p − 6| + p = 6.



thanks Bunuel..i have got it now... i wasn't seeing it the right way!!

You are wrong here Ashu,

There can be infinite many answers for this equation and the answer will fall in the range 0<p<6

I hope it answers your query!

It's simple property of Absolute Value: if \(|x| = y\), then \(y>= 0\);

Here the given equation can be rearranged as, \(|p-6| = 6-p\)
which implies, \(6-p >=0\)
or \(p<=6\). Hence E.

I hope this clarifies some doubts.
