Choose the correct choice from the following choices
A) 0  B) 2  C) 4  D) 8  E) More than 8
I think its 8   |||B-5|-10|-5| =2   let |B-5| = a which makes above   ||a-10|-5| =2   let |a-10| = b which makes   |b-5| = 2   now for the above b can take 3, 7   for every b =3 a can have 13, 7   and for b = 7 a can have 17 and 3   so 'a' has four solutions 13, 7, 17 and 3   for a = 13; x has 18 or -8 thus has 2 for every combination hence 4x2 = 8   answer 8
