Select the number that will come in the place of the question mark (?), if ‘+’ and ‘-’ are interchanged and ‘x’ and ‘÷’ are interchanged. 11 × 8 ÷ 5 + 30 − 50 = ?
27
When we interchange '+' and '-' and 'x' and '÷', the equation becomes: 11 ÷ 8 × 5 − 30 + 50. Solving this, we get:
11 ÷ 8 = 1.375
1.375 × 5 = 6.875
6.875 − 30 = -23.125
-23.125 + 50 = 26.875
The correct answer is 27.
