What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘×’ are interchanged and ‘÷’ and ‘−’ are interchanged?
35 ÷ 4 + 6 − 3 × 12 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 39.
Given equation: 35 ÷ 4 + 6 − 3 × 12 = ?
On interchanging the sign:
35 - 4 × 6 ÷ 3 + 12 = ?
? = 35 - 8 + 12
? = 47 - 8 = 39
