What will come in the place of the question mark (?) in the following equation if ‘÷’ and ‘+’ are interchanged and ‘−’ and ‘×’ are interchanged?
17 ÷ 27 × 7 − 9 + 3 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 23.
Given equation: 17 ÷ 27 × 7 − 9 + 3 = ?
After interchanging the signs:
17 + 27 - 7 × 9 ÷ 3 = ?
? = 17 + 27 - 21
? = 44 - 21 = 23
