  • Question
  • What should come in place of question mark (?) in the following question? 1234 + 2345 ? 3456 + 4567 = ?


  • Options
  • A. 4590
  • B. 4680
  • C. 4670
  • D. 4690

  • Correct Answer
  • 4690 

    Explanation

    As per the BODMAS rule, the priority in which the operations should be done is:

    Priority wise operations Symbol
    B-Bracket ()
    O-of of
    D-Division /,÷
    M-Multiplication *,x
    A-Addition +
    S-Subtraction -

    Note: Addition and subtraction can be treated on same priority (from left to right) when they are in consecutive order. ? = 1234 + 2345 ? 3456 + 4567 ? = 3579 - 3456 + 4567 ? = 123 + 4567 ? = 4690
