What will come in the place of the question mark (‘?’)in the following equation, if ‘+’ and ‘×’ are interchanged and ‘÷′ and ‘–‘ are interchanged?
19 × 7 ÷ 8 × 306 – 17 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 36.
Given equation: 19 × 7 ÷ 8 × 306 – 17 = ?
On interchanging the signs:
19 + 7 - 8 + 306 ÷ 17 = ?
? = 19 + 7 - 18
? = 26 - 18 = 8
