# p is defined as 2 p - 20 for any number p . what is p , if # ( # ( # p ) ) = 12 ?
# p = 2 p - 20 - - - > # ( # p ) = 2 ( 2 p - 20 ) - 20 = 4 p - 60 and thus # ( 4 p - 60 ) = 2 ( 4 p - 60 ) - 20 = 8 p - 140 = 12 - - - > 8 p = 152 - - - > p = 19 , b is the correct answer .
divide(add(add(20, multiply(20, 12)), 12), multiply(2, const_4))
