Question
In the following equations, if ‘+’ is
interchanged with ‘—’ and ‘6’ is interchanged with ‘7’, then which equation would be correct?Solution
From the option A, 67 - 76 + 43 = 100 On the interchanging, 76 + 67 - 43 = 100 143 - 43 = 100 100 = 100 The correct answer is option A.
What will come in place of the question mark (?) in the following series?
