What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
14 ÷ 7 − 27 × 9 + 12 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 89.
Given equation: 14 ÷ 7 − 27 × 9 + 12 = ?
If ‘+’ and ‘–‘ are interchanged and ‘×’ and ‘÷’ are interchanged, then
= 14 × 7 + 27 ÷ 9 − 12
= 14 × 7 + 3 − 12
= 98 + 3 − 12
= 101 − 12
= 89
