What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
1604 × 4 + 87 – 16 ÷ 16 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 570.
Given equation: 1604 × 4 + 87 – 16 ÷ 16 = ?
On interchanging the signs:
1604 ÷ 4 - 87 + 16 × 16 = ?
? = 401 - 87 + 256 = 657 - 87 = 570
