What will come in the place of the question mark (?) in the following equation, if '+' and '÷' are interchanged and '-' and '×' are interchanged?
44 ÷ 78 + 6 − 3 × 19 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 64.
Given equation: 44 ÷ 78 + 6 − 3 × 19 = ?
On interchanging the signs:
44 + (78 ÷ 6) × 3 - 19 = ?
? = 44 + (13 × 3) - 19
? = 44 + 39 - 19
? = 83 - 19 = 64
