Which number will come in the place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
14 − 45 × 5 + 6 ÷ 3 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 5.
Given equation: 14 − 45 × 5 + 6 ÷ 3 = ?
On interchanging the signs:
14 + (45 ÷ 5) - (6 × 3) = ?
? = 14 + 9 - 18
? = 23 - 18
? = 5
