What will come in place of the question mark (?) in the following equation if ‘÷’ and ‘-’ are interchanged and ‘×’ and ‘+’ are interchanged?
2 × 16 ÷ 36 + 42 - 6 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. -234.
Given equation: 2 × 16 ÷ 36 + 42 - 6 = ?
On interchanging the signs:
2 + 16 - {36 × (42 ÷ 6)} = ?
? = 2 + 16 - 252
? = 18 - 252
? = -234
