What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
1064 × 2 – 653 ÷ 2 + 89 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1749.
Given equation: 1064 × 2 – 653 ÷ 2 + 89 = ?
On interchanging the signs:
1064 ÷ 2 + 653 × 2 - 89 = ?
? = 532 + 1306 - 89
= 1838 - 89 = 1749
