If - means x, x means +, + means 4, and + means then 40x 12 + 3- 6 + 60 = ?

  • A.7.95         
  • B.16           
  • C.44            
  • D.None of these

Answer: D

Correct answer: None of these

Substituting turns the expression into one whose value falls outside every figure offered, so the answer is none of them. The stem’s list of definitions has been damaged - one sign appears against two different operations - but on any consistent reading of it the result is a value the three numbered options do not contain.
