Which two signs should be interchanged to make the given equation correct?
12 ÷ 5 - 8 x 2 + 14 = 70
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ÷ and x.
From option (3): ÷ and ×
Given equation ⇒ 12 ÷ 5 - 8 × 2 + 14 = 70
After interchanging the signs:
⇒ 12 × 5 - 8 ÷ 2 + 14 = 70
Apply BODMAS rule:
⇒ 12 × 5 - (8 ÷ 2) + 14 = 70
⇒ (12 × 5) - 4 + 14
⇒ 60 - 4 + 14
⇒ 74 - 4
= 70
Hence, the correct answer is ÷ and x.
