Which two signs should be interchanged to make the given equation correct?
15 ÷ 9 × 8 + 12 − 4 = 17
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. + and ÷.
Given equation: 15 ÷ 9 × 8 + 12 − 4 = 17
2) + and ÷
⇒ 15 + 9 × 8 ÷ 12 - 4 = 17
⇒ 15 + 9 × 2/3 - 4 = 17
⇒ 15 + 6 - 4 = 17
⇒ 21 - 4 = 17
⇒ 17 = 17
Thus, this satisfies the equation.
Hence, the correct answer is + and ÷.
