What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
17 ÷ 4 - 28 + 125 × 5 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 71.
Given equation: 17 ÷ 4 - 28 + 125 × 5 = ?
On changing the signs:
(17 × 4) + 28 - (125 ÷ 5) = ?
? = 68 + 28 - 25
? = 96 - 25
? = 71
