What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘-‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
25 + 3 ÷ 9 -14 × 2 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5.
Given equation: 25 + 3 ÷ 9 -14 × 2 = ?
On interchanging the signs:
25 - 3 × 9 + (14 ÷ 2) = ?
? = 25 - (3 × 9) + 7
? = 25 - 27 + 7
? = 32 - 27 = 5
