What will come in the place of ‘?’ in the following equation if ‘+’ and ‘×’ are interchanged and ‘–’ and ‘÷’ are interchanged?
21 – 7 × 26 + 46 ÷ 36 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1163.
Given equation: 21 – 7 × 26 + 46 ÷ 36 = ?
On interchanging the signs:
(21 ÷ 7) + (26 × 46) - 36 = ?
? = 3 + 1196 - 36
? = 1199 - 36 = 1163
