What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
6408 × 8 + 27 – 15 ÷ 10 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 924.
Given equation: 6408 × 8 + 27 – 15 ÷ 10 = ?
On changing the signs:
6408 ÷ 8 - 27 + 15 × 10 = ?
? = 801 - 27 + 150
? = 951 - 27 = 924
