Which of the following equations is correct when the numbers 12 and 6 are interchanged and the signs ÷ and + are interchanged?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6 ÷ 4 × 5 - 12 + 3 = 30.
Option 4) 6 ÷ 4 × 5 - 12 + 3 = 30
When the numbers 12 and 6 are interchanged and the signs ÷ and + are interchanged,
⇒ 12 + 4 × 5 - 6 ÷ 3 = 30
⇒ 12 + 4 × 5 - 2 = 30
⇒ 12 + 20 - 2 = 30
⇒ 32 - 2 = 30
⇒ 30 = 30
