What will come in place of the question mark (?) in the following equation if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
121 + 1 – 6 ÷ 16 × 8 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 132.
Given equation: 121 + 1 – 6 ÷ 16 × 8 = ?
On interchanging the signs:
121 - 1 + 6 × 16 ÷ 8 = ?
? = 121 - 1 + 12
? = 133 - 1 = 132
