What will come in place of the question mark ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
13 + 4 × 2 ÷ 5 – 2 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5.
Given equation: 13 + 4 × 2 ÷ 5 – 2 = ?
If ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged, then
= 13 - 4 ÷ 2 × 5 + 2
= 13 - 2 × 5 + 2
= 13 - 10 + 2
= 15 - 10
= 5
