    β€˜Γ—β€™ means β€˜+’, and β€˜Γ·β€™ means β€˜βˆ’β€™, then what will come in place of the question mark (?) in the following equation? 72 Γ— 6 + 12 βˆ’ 4 Γ· 8 = ?
    A 80 Correct Answer Incorrect Answer
    B 82 Correct Answer Incorrect Answer
    C 76 Correct Answer Incorrect Answer
    D 84 Correct Answer Incorrect Answer

    Solution

    Given conditions: β€˜+’ means β€˜Γ—β€™ β€˜βˆ’β€™ means β€˜Γ·β€™ β€˜Γ—β€™ means β€˜+’ β€˜Γ·β€™ means β€˜βˆ’β€™ Transforming the expression: Given equation: 72 Γ— 6 + 12 βˆ’ 4 Γ· 8 = ? After replacing the symbols based on the given conditions: = 72 + 6 Γ— 12 Γ· 4 βˆ’ 8 = 72 + 72 Γ· 4 βˆ’ 8 = 72 + 18 βˆ’ 8 = 90 βˆ’ 8 = 82 Hence, option 2 is the correct answer.
