What will come in the place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
108 × 2 − 14 ÷ 6 + 27 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 111.
Given: 108 × 2 − 14 ÷ 6 + 27 = ?
When ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged, then
108 ÷ 2 + 14 × 6 - 27 = ?
= 54 + 14 × 6 - 27
= 54 + 84 - 27
= 111
