What will come in place of the question mark (?) when + and − are interchanged?
8 − 3 × 4 + 16 ÷ 2 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 12.
Given equation: 8 − 3 × 4 + 16 ÷ 2 = ?
When + and − are interchanged then:
8 + 3 × 4 - 16 ÷ 2 = ?
? = 8 + 3 × 4 - 8
? = 8 + 12 - 8 = 12
