What will come in the place of the question mark (?) in the following equation, if +' and '÷' are interchanged and '- and '×' are interchanged?
28 ÷ 90 + 6 - 5 × 17 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 86.
Given : 28 ÷ 90 + 6 - 5 × 17 = ?
On interchanging the signs:
⇒ 28 + (90 ÷ 6) × 5 - 17 = ?
⇒ ? = 28 + (15 × 5) - 17
⇒ ? = (28 + 75) - 17
⇒ ? = 103 - 17
⇒ ? = 86
