For how many values of N, is |||N - 5| -10| -5| = 2?
(Those ls are mods)
Choose the correct choice from the following answers
A) 0 B) 2 C) 4 D) 8 E) more than 8

Rationale: i think its 8 | | | n - 5 | - 10 | - 5 | = 2 let | n - 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 4 x 2 = 8 answer d
Answer: D
