Which two signs should be interchanged to make the given equation correct?
30 + 3 × 990 − 11 ÷ 63 = 237
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ÷ and −.
30 + 3 × 990 − 11 ÷ 63 = 237
After interchanging the mathematical sign we get;
⇒ 30 + 3 × 990 ÷ 11 - 63 = 237
⇒ 30 + 3 × 90 - 63 = 237
⇒ 30 + 270 - 63 = 237
⇒ 237 = 237
