What will come in the place of the question mark (?) in the following equation if '+' and '-' are interchanged and '×' and '÷' are interchanged?
104 - 7 ÷ 65 × 13 + 38 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 101.
Given equation: 104 - 7 ÷ 65 × 13 + 38 = ?
After interchanging the signs:
104 + 7 × (65 ÷ 13) - 38 = ?
⇒ 104 + (7 × 5) - 38
⇒ 104 + 35 - 38
⇒ 104 - 3
⇒ 101
