What will come in the place of ‘?’ in the following equation if ‘×’ and ‘–’ are interchanged and ‘+’ and ‘÷’ are interchanged?
36 + 18 × 9 ÷ 13 – 19 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 240.
Given equation: 36 + 18 × 9 ÷ 13 – 19 = ?
On interchanging the signs:
36 ÷ 18 - 9 + 13 × 19 = ?
? = 2 - 9 + 247
? = 249 - 9 = 240
