    Directions: The two expression on either side of the sign (=) will have the same value if two terms on either side or on the same side are interchanged. The correct terms to be inter-changed have been given as one of the four alternatives under each expressions. Find the correct alternative. By applying which of the following meanings of arithmetical signs, will the value of \[\mathbf{700}\,\,\mathbf{-}\,\,\mathbf{10}\,\,\mathbf{+}\frac{\mathbf{1}}{\mathbf{2}}\,\,\mathbf{\times }\,\,\mathbf{35}\,\,\mathbf{+}\,\,\mathbf{70}\] be zero?

    A) \[\times \] means \[\div \], + means \[\times \], \[\div \] means +, - means ?

    B) \[\times \] means \[\div \], + means -, \[\div \] means -, means \[\times \], - means +

    C) \[\times \] means +, + means \[\times \], \[\div \] means \[\times \], - means \[\div \]

    D) \[\times \] means \[\div \], + means -, \[\div \] means \[\times \], - means +

    Correct Answer: C

    Solution :

    (c) Using the operations given in (c), we get the given expression as: \[700-10\,\,\times \,\,\frac{1}{2}+35-70\]
