What will come in the place of ‘?’ in the following equation, if ‘×’ and ‘ ÷ ‘ are interchanged and ‘–’ and ‘+’ are interchanged?
23 ÷ 18 + 150 × 50 – 44 = ?
Show answer & explanation
Correct answer: D
Explanation

Given equation: 23 ÷ 18 + 150 × 50 – 44 = ?
On interchanging the sings:
23 × 18 - 150 ÷ 50 + 44 = ?
? = 414 - 3 + 44
? = 458 - 3 = 455
