What will come in place of the question mark (?) when + and − are interchanged and 8 and 16 are also interchanged?
3 × 6 + 16 − 8 ÷ 2 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 18.
3 × 6 + 16 − 8 ÷ 2 = ?
After interchanging the mathematical sign and number we get;
= 3 × 6 - 8 + 16 ÷ 2
= 3 × 6 - 8 + 8
= 18 - 8 + 8
= 18
Hence, the correct answer is 18.
