Which two signs should be interchanged to make the given equation correct?
256 - 4 x 2 + 200 ÷ 19 = 309
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ÷ and -.
From option (3): ÷ and -
Given equation:
256 - 4 × 2 + 200 ÷ 19 = 309
After interchanging the signs:
⇒ 256 ÷ 4 × 2 + 200 - 19 = 309
Apply using the BODMAS rule:
⇒ 64 × 2 + 200 - 19
⇒ 128 + 200 - 19
⇒ 328 - 19 = 309
Hence, the correct answe is ÷ and -.
