What will come in place of the question mark (?) in the following equation if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
12 ÷ 2 × 6 – 11 + 12 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3.
Given equation: 12 ÷ 2 × 6 – 11 + 12 = ?
‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged, then
= 12 × 2 ÷ 6 + 11 – 12
= 4 + 11 – 12
= 15 – 12
= 3
