What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged?
78 − 6 ÷ 6 + 2 × 8 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 9.
Given equation: 78 − 6 ÷ 6 + 2 × 8 = ?
