What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
(14 ÷ 2) – (16 × 4) + 12 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e., 20.
(14 ÷ 2) – (16 × 4) + 12 = ?
After interchanging the sign,
= (14 × 2) + (16 ÷ 4) - 12
= 28 + 4 - 12
= 28 - 8
= 20
