Which two signs should be interchanged to make the given equation correct?
29 + 12 - 4 × 40 ÷ 5 = 49
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. + and -.
29 + 12 - 4 × 40 ÷ 5 = 49
After interchanging signs,
⇒ 29 - 12 + 4 × (40 ÷ 5) = 49
⇒ 17 + (4 × 8) = 49
⇒ 17 + 32 = 49
⇒ 49 = 49
Hence, the correct answer is + and -.
