What will come in the place of the question mark (?) in the following equation if '+' and '-' are interchanged and '×' and '÷' are interchanged?
73 - 27 × 9 + 5 ÷ 13 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 11.
Given equation: 73 - 27 × 9 + 5 ÷ 13 = ?
If '+' and '-' are interchanged and '×' and '÷' are interchanged:
73 + 27 ÷ 9 - 5 × 13 = ?
? = 73 + 3 - 65
? = 76 - 65 = 11
